An Overview: Choosing the Right Grade of Stainless Steel for Your Project

As most stainless steel fabricators in Perth will tell you, the grade of stainless steel you choose can make or break your project. Without becoming overly technical, here is a quick guide to choosing the correct grade of stainless steel for your project.

Choosing the Right Grade of Stainless Steel

The Benefits of Stainless Steel

Stainless steel is very resistant to corrosion due to the fact that it is made of at least 12% chromium. This reacts with oxygen to produce a thin oxide layer that makes it impossible for it to rust. It also makes it easy to clean and keep sanitary. This corrosion resistant film makes stainless steel indispensable to the chemical, pharmaceutical and food industries.

Stainless steel is able to be easily formed and processed into many different shapes for many different applications. It can be processed into wire, seamless tubing, plates, bars, sheets and strips. Stainless steel is available in many different types and grades. Here are the three main types.

Austenitic

Austenitic stainless steel can be in the 300 series, which consists of steel with chromium and nickel, or the 200 series, which consists of steel with chromium and manganese. Austenitic stainless steels are the most popular and contain at least 16% chromium. They have a maximum of 0.15% carbon. The addition of nickel and manganese helps them keep their austenitic structure at any temperature up to their melting point.

Some common applications are electrical enclosures, cooking utensils and building construction.

Martensitic

Martensitic stainless steels contain between 12% and 14% chromium with nickel, molybdenum and carbon. They don’t provide the corrosion resistance that austenitic stainless steels do, but they are tough, machinable and can be made very hard by heat treatment. Due to this hardness, they are used for cutlery, food processing blades, valves, shafts and fasteners.

Duplex stainless steels combine austenitic stainless steel with ferritic stainless steel. They contain 19-28% chromium with molybdenum, nickel and small, variable amounts of other elements.

They are widely used in the petrochemical, chemical, marine, paper and pulp industries.

Why Stainless Steel is so Popular in the Hospitality Industry

As one of the most prolific stainless steel suppliers in Perth, we have installed stainless steel equipment in a lot of restaurants, pubs, commercial kitchens and industrial kitchens. In the hospitality industry, stainless steel is the material of choice for many applications due to its cleanability, durability and appearance.

Restaurants are subject to extremely high sanitation standards. One mistake in sanitation can lead to many people becoming sick. Consequently, kitchen owners want a material that is easy to keep sanitary. Stainless steel is the best material for kitchen applications because it is non-porous.

Properties of Stainless Steel

Stainless steel is non-corrosive due to its chromium content. Thanks to a property that is called “passivity,” the surface of stainless steel is self-repairing. The addition of other materials such as nickel and molybdenum further enhances the non-corrosive nature of stainless steel.

Stainless steel is also a very smooth, non-porous surface. That makes it easy to clean because organic materials can’t gain a “foothold” on the surface. The fact that stainless steel is non-porous allows it to be more thoroughly cleaned than porous materials.

Stainless steel is more durable and can bear a heavier load than many metals. Because of this, a stainless steel countertop or bench weighs less than other materials of similar strength. Stainless steel is easily fabricated into bespoke solutions and the cost of maintenance, repair or replacement is lower than that of most other materials.

Some Uses for Stainless Steel in the Hospitality Industry

One can almost outfit an entire kitchen in stainless steel. Pots, pans, tables, benches, sinks, food holding equipment, refrigerators, walk-in coolers and utensils can all be made of stainless steel. For large food processing facilities, hoppers and pipes for transport can also be made of stainless steel.

Why Stainless Steel is the Preferred Material for So Many Applications

We have undertaken a lot of custom design stainless steel installation projects in the Perth area. Stainless steel is extremely popular in the hospitality, medical, sanitation, mining, mechanical and commercial sectors. We would like to tell you why.

Why Stainless Steel is the Preferred Material for So Many Applications

High Corrosion Resistance

Stainless steel provides high corrosion resistance in many different applications. A lower alloyed grade can be used for pure water and atmospheric environments, while a high alloyed grade is perfect for alkaline solutions, acids and chlorine bearing environments. This makes it the material of choice in most process plants.

Fire and Heat Resistance

High chromium and nickel-alloyed stainless steel grades retain their strength and resist scaling at high temperatures.

Hygiene

Stainless steel is the easiest metal to clean. This makes it the preferred material for all applications requiring strict hygiene, such as kitchens, hospitals and food processing plants.

Appearance

Stainless steel is bright and easy to keep that way. It can lend an attractive and modern look in numerous situations.

High Strength to Weight Ratio

Because austenitic grades have a work-hardening property that allows them to be strengthened through cold-working, they provide a great strength to weight ratio. Duplex grades allow you to reduce the material thickness in many applications without losing any strength. The end result: it saves money.

Easily Fabricated

As stainless steel fabricators in Perth know, stainless steel is easily fabricated. It can be formed, cut, welded and machined as easily as standard steel.

Long Term Value

Because stainless steel is so durable and resistant to corrosion, it lasts longer than other materials used for similar tasks. This provides long term value.

What You Need to Know About Stainless Steel Grates

Stainless steel fabricators in Perth produce a lot of grandiose equipment for many medical, industrial and hospitality applications. One of the most overlooked is the stainless steel grate. Stainless steel grates are used as grease filters in kitchen canopies, but are used more commonly in liquid transfer applications where filtering is needed.

What You Need to Know About Stainless Steel Grates

Stainless steel is especially effective in food processing environments because it is non-porous and easily cleaned, ensuring that they won’t cause airborne bacteria as grates of other materials could. Stainless steel is the material of choice in the food industry because sanitation is so important. Stainless steel is easily kept sanitary, which is essential in any food or medical application.

Stainless steel grates are also used in the transfer of water or corrosive liquids because it is corrosion-resistant. It doesn’t rust and it isn’t corroded by most corrosive materials. This allows it to filter a wide range of fluids with no degradation of the stainless steel and no contamination of the liquid being filtered.

A Sampling of Industries using Stainless Steel Grates

Stainless steel grates have many other applications. As mentioned, they are used for food processing, water processing and in the chemical industry. They are also used in the mining industry, oil refineries, steel plants, wastewater facilities, machinery plants, cement plants, the pharmacy industry and civil engineering.

Basically, wherever there is a need for drainage filters, stainless steel is the best solution.

Commercial Exhaust Hood Selection and Maintenance

As the foremost stainless steel suppliers and fabricators in Perth, we have created and installed a lot of exhaust hoods for bar, restaurant, commercial and hospital kitchens. Consequently, we have had plenty of time to perfect our operation. We have also had plenty of time and experience to figure out what works and what doesn’t.

Commercial Kitchen Exhaust Hoods

Types of Exhaust Hoods

It is extremely important to make the right equipment choices when selecting or creating an exhaust hood. Exhaust hoods come in various shapes and sizes. They can be vented or unvented. Vented hoods draw air into the hood from the kitchen area and then direct it through a series of pipes and/or ducts away from the kitchen area, outdoors.

On the other hand, a ventless hood draws air from the kitchen area through a series of filters that clean the air. The air is then recirculated back into the kitchen.

If you have a vented hood, it will usually need to be cleaned professionally. There are specific protocols and procedures that must be followed. Some require special tools to do the job correctly and keep the hood functioning at its optimum safety and efficiency. Different types of commercial exhaust hoods have different cleaning schedules.

How to Clean

A ventless hood often doesn’t need to be professionally cleaned. This is because they are less efficient and do not circulate or clean the volume of air that a vented hood would clean. Consequently, ventless hoods are not appropriate for use in high volume kitchens.

However, ventless hoods do employ charcoal filters that cannot be cleaned. Those filters must be replaced at regular intervals depending upon the type and volume of cooking that is performed in the kitchen. Kitchens that have fryers and grills require more frequent changing of filters because of the higher amount of grease that builds up.

The charcoal filters are usually available at your favourite appliance store. However, you must take care that you are purchasing the correct filter for your ventless hood.

The exterior portions of both vented and unvented hoods should be cleaned daily. Vented hoods will be more difficult to clean because they will usually have more grease on them than a ventless hood.

It is recommended that you always have a professional clean the interior portion of a vented hood. Professionals know the methods and materials necessary to thoroughly clean the interior of a vented hood without causing any damage to the stainless steel surface. This ensures years of high quality performance.

Bacterial Buildup and Local Regulations

Due to the possibility of bacterial or fungal buildup on exhaust hoods, different locations have different regulations pertaining to how often the interior of vented exhaust hoods must be cleaned. These regulations are helpful, as they help you keep your exhaust hood running efficiently, thus increasing its lifespan.

Bacteria and mould can compromise the safety of your kitchen, exposing your staff and customers to dangerous microorganisms. To keep this from occurring, it is essential to have your exhaust hood cleaned on a regular schedule.

The maximum that a system should ever go without being cleaned is six months, but we recommend that professional cleaning is done much more frequently. The amount of volume produced in your kitchen will determine how much buildup is inside of your hood and how often it needs to be cleaned.

If your kitchen has fryers, charcoal broilers and grills, there will be a lot more build-up inside of your hood and it should be cleaned as frequently as possible. However, don’t think that a “slow” kitchen allows you the luxury of skipping scheduled cleanings. Even a slow kitchen is still subject to bacteria and mould.

Symptoms of Insufficient Cleaning

If you fail to keep the interior of your exhaust hood clean, you are exposing your employees and customers to dangerous microorganisms. Your staff will suffer more because they are there longer and many work beneath the hood.

Common symptoms of bacterial or fungal exposure are frequent or chronic respiratory or gastrointestinal illnesses.

Helping the Kids: New Children’s Hospital in Perth

Currently, we are involved in a project that we feel we received because we are one of the best stainless steel fabricators in Perth: the Perth Children’s Hospital.

Stainless Steel Manufacturer Helping Perth Children Hospital

The medical industry requires that every piece of equipment is 100% perfect. There is no room for error in the medical industry because their standard of sanitation is the highest of any sector of business. If a company provides a piece of stainless steel equipment that doesn’t retain its structural integrity at all times, it can allow bacteria, viruses or fungi to contaminate equipment, personnel and patients.

In other words, if we make mistakes or take shortcuts, somebody could die as a result of our actions. That is why the medical industry is very picky and thorough when deciding which custom stainless steel manufacturer they will allow to manufacture and install their equipment. That is also why the Perth Children’s Hospital chose Western Stainless Solutions for this marquee project.

We worked very hard with John Holland to secure the stainless steel joinery for this project and are proud to be a part of creating the Perth Children’s Hospital. We will be providing a variety of benches on this project, under strict deadlines and the aforementioned stringent standards.

We are known within the industry for our work at other hospitals and medical facilities because our work exceeds every known medical standard for sanitation and structural integrity. We combine modern materials and meticulous design to exceed those standards, such as the State Health Department’s Infectious Control Standards.

This is why we have become the preferred stainless steel fabricators in Perth, with numerous projects both in Perth and in other parts of WA.

Promoting Corrosion Resistance and Cleanability in Your Stainless Steel

Two of the defining features for stainless steel are its ability to be resistant to decay and corrosion and its ability to be easily cleaned. These are important aspects for the metal to have as it is often used in pharmaceutical, industrial and food production settings. Heat tint is the greatest threat to stainless steel and can cause damages that cause many problems for owners of these appliances. Luckily, it can also be prevented through a process known as purge welding.

Promoting Corrosion Resistance and Cleanability in Your Stainless Steel

A Heated Problem

Heat tint is the oxide buildup that occurs in stainless steel tubes when it is welded without expelling all of the oxygen first. While not overly damaging at first, the discolouration and corrosion created by heat tint can spread and cause more destruction in the form of increased corrosion and infestation of bugs.

Under normal circumstances, gas can be forced to flow into the metallic area if access is easily granted. However this is highly impractical, if not impossible, when the stainless steel object is a pipe with a small diameter. For these objects, there is another method that is most useful for getting rid of heat tint.

The Purge

Purge welding is a very useful process for minimising or eliminating heat tint in hard to reach places. It works by controlling oxygen levels when the steel inside is heated considerably. Then a tiny weld is manoeuvred inside of the pipeline and thus allowing the heat tint to be worked away.

It may sound simple, but purge welding takes a steady hand and experienced skill. If performed correctly, it ensures that the stainless steel will keep on shining for a long time to come, making it as resilient and cleanable as it was meant to be.

Corrosion-Resistant

While stainless steel is one of the best materials to use in pharmaceutical and food producing environments, there are still threats to this material in the form of heat tint. Thankfully, this can be minimised or avoided through purge welding, which greatly reduces heat tint and keeps the steel strong. This can be a tricky process, so be sure to consult professional stainless steel fabricators in your Perth area if you are uncertain.
