Benefits of Using Stainless Steel


Stainless steel is a very strong and durable material. It is resistant to corrosion and can withstand a wide range of temperatures.


Stainless steel is a non-porous material, which means that it does not harbor bacteria or other harmful microorganisms. 

This makes it ideal for use in food service and healthcare settings.

Easy to Clean

Stainless steel is a very easy material to clean. It can be wiped down with a damp cloth or washed with soap and water.


Stainless steel is a sleek and modern material that looks great in any setting.

Stainless Steel Frequent Asked Questions (FAQs)

What Types of Stainless Steel Finishes?
1 Finish is produced by rolling stainless steel that has been heated before rolling (hot-rolling). This is followed by a heat treatment that produces a uniform microstructure (annealing) and ensures that the stainless steel will meet mechanical property requirements. This finish is mainly used for industrial applications such as furnace arch supports, furnace conveyors, furnace linings, air heaters, boiler baffles, incinerators, kiln liners, and industrial oven liners, among many others.

2B Finish is the term used by the ASTM A480 standard to define “a smooth, moderately reflective cold-rolled annealed and pickled or descaled finish typically produced by imparting a final light cold-rolled pass using polished rolls.” It is the most widely-used stainless steel finish available today. It’s often used for everything from flatware, bakeware, and pharmaceutical equipment to plumbing fixtures, sheet metal products, and solar collector panels.

2D Finish is a refined surface finish achieved by cold rolling, heat treating, and pickling. This is a uniform, dull silver-grey finish that is rougher than the 2B Finish. Pickling or descaling is necessary after heat treatment to remove the chromium-depleted dark surface layer and restore corrosion resistance. Applications include roofing, petrochemical equipment, and electric range parts.

4B Finish is produced by rolling the sheets of stainless steel between polished rollers. It commonly has a slightly matte or frosted appearance. The surface is usually very smooth but the Ra’s can be all over the place and still meet the spec. It is often used on average restaurant or kitchen equipment, food processing or dairy equipment, and elsewhere. 

Bright Annealed (BA) Finish is cold rolled stainless steel that is annealed in a controlled atmosphere to retain a highly reflective finish. Although it is not completely identical to the #8 mirror finish, it appears to be very similar. Applications include surgical instruments, fishing equipment,
cookware, automobile trim, chute liners and textile finishing equipment.

Mirror Finish is a highly reflective, smooth finish with a scratch-free appearance, achieved through polishing the stainless steel. Also known as a #8 finish, a mirror finish can be achieved mechanically, using a progressive series of abrasives and polishing compounds. The application includes clean rooms (countertops, wall panel doors, handles), food processing, pharmaceutical, life science operations, and machinery that must remain sterile (medical equipment manufacturing, pharmaceutical manufacturing, food processing, and brewing.)
Whats is the Differences between Cold Rolled Steel & Hot Rolled Steel?
Customers often ask us about the differences between hot rolled steel and cold rolled steel. There are some fundamental differences between these two types of metal. The differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill, and not the product specification or grade. Hot rolled steel involves rolling the steel at high temperatures, where cold rolled steel is processed further in cold reduction mills where the material is cooled followed by annealing and/ or tempers rolling.

Hot Rolled Steel
Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel’s recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes. Hot rolled steel is typically cheaper than cold rolled steel due to the fact that it is often manufactured without any delays in the process, and therefore the reheating of the steel is not required (as it is with cold rolled). When the steel cools off it will shrink slightly thus giving less control on the size and shape of the finished product when compared to cold rolled.

Cold Rolled Steel
Cold rolled steel is essentially hot rolled steel that has had further processing. The steel is processed further in cold reduction mills, where the material is cooled (at room temperature) followed by annealing and/or tempers rolling. This process will produce steel with closer dimensional tolerances and a wider range of surface finishes. The term Cold Rolled is mistakenly used on all products, when actually the product name refers to the rolling of flat rolled sheet and coil products. 

When referring to bar products, the term used is “cold finishing”, which usually consists of cold drawing and/or turning, grinding and polishing. This process results in higher yield points and has four main advantages: Cold drawing increases the yield and tensile strengths, often eliminating
further costly thermal treatments.
Turning gets rid of surface imperfections.
Grinding narrows the original size tolerance range.
Polishing improves surface finish.

All cold products provide a superior surface finish, and are superior in tolerance, concentricity, and straightness when compared to hot rolled.

Cold finished bars are typically harder to work with than hot rolled due to the increased carbon content. However, this cannot be said about cold rolled sheet and hot rolled sheet. With these two products, the cold rolled product has low carbon content and it is typically annealed, making it softer than hot rolled sheet.
304 vs 316 Stainless Steel
While the two most popular grades of stainless steel might seem identical at a glance, they hold important differences that can lead to substantial savings over the life of your product depending on your intended uses.

All stainless steels contain a mix of iron and chromium at various levels. But the exact mix—and other additions — are what create the differences between grades.

The most popular 304 grade stainless contains 18% chromium and 8% nickel — though other alloys exist within the same grade.

Stainless steels of the 316 grade include less chromium — often around 16% — but increase nickel levels and add molybdenum to the mix.

In most common alloys, you’ll find 10% nickel and 2 to 3% molybdenum. However, specialty alloys might have as much as 9% molybdenum.

Most stainless steel ordered around the world is Grade 304. It offers the standard corrosion resistance, formability, strength, and easy maintenance for which stainless is known.

While 316 comes in second in terms of quantities sold, it offers vastly
superior corrosion resistance to chlorides and acids.

This makes it popular for a wide range of environments—including:
-Medical equipment and implants
-Foodservice, processing, and preparation environments
-Coastal environments
-Areas with high salt levels (such as roadways)
-Brewing facilities
-Environments with increased exposure to alkalis and acids

These increased resistances also help to take the guesswork out of cleaning and allow you to clean your stainless more often using stronger cleansers and detergents with little worry of damage or altering the appearance of the stainless steel.

This makes 316 an ideal upgrade for environments with strict hygiene and cleanliness standards.


With the benefits offered by 316 stainless steel, you might wonder why 304 remains the most popular...

If you’re not sure which to choose, consider these common uses for the two grades:

-Water piping
-Storage tanks
-Indoor electrical enclosures
-Wheel covers
-Automotive trim
-Kitchen equipment
-Decorative trim

-Chemical piping
-Pharmaceutical equipment
-Medical equipment
-Chemical equipment
-Stainless steel floats
-Structural steel and components in marine environments
-Commercial kitchen surfaces, equipment, and appliances

In short, it’s mostly about cost and corrosion resistance requirements. If you don’t need the added resistance of 316, standard 304 grades will offer similar performance and longevity at a lower price point.

However, in situations where the added resistance is needed, 316 often improves the functional lifespan of the steel products by years.

This can lead to drastic long-term savings despite the initial increase in investment.
