What’s The Difference Between Cold Rolled and Stainless Steel?
The better understanding you have of the different types of steel used for industrial construction projects, the easier it’ll be for you to source the right steel for your work.
Although the difference between cold rolled and hot rolled steel is often talked about, the difference between cold rolled steel and stainless steel can also be confusing. So what are the differences between these two metals?
Key differences in cold rolled and stainless steel
The main difference between these two metals is that stainless steel is an alloy made up of steel and other elements such as carbon, aluminum, silicon, nickel, molybdenum, and chromium. Iron is the main component of stainless steel and the chromium that’s added makes it resistant to rust.
Cold rolled steel isn’t an alloy or a specific type of steel. It’s a process used to finish steel that begins with hot rolled steel. Tension from the power rollers is added to the steel sheet during the cold rolling process to deliver a harder and thinner product.
In terms of their properties, both stainless steel and cold rolled steel offer a strong, light product. However, they differ when it comes to corrosion resistance.
Stainless steel is highly resistant to corrosion, which makes it ideal for projects such as aircraft construction and building development. Cold rolled steel isn’t as resistant to corrosion, which is why it’s often used in areas where corrosion isn’t likely to happen.
Cold rolled steel is used for engineered products which require coated surfaces and tight tolerances such as parts that need to bend. Products that typically use cold rolled steel include:
- Machinery parts
- Stamped parts
- Building frames
- Exposed automotive components
- Exposed aircraft components
- Stoves and ovens
- Washers and dryers
- Small appliances
- Deep-drawn shells
What’s more, unlike stainless steel, cold rolled steel also comes available in four types because it’s a process and not an alloy. There’s commercial steel, drawing steel, extra deep drawing steel, and extra deep drawing steel plus. Drawing steel is considered more ductile than the others.
Need cold formed sheet piling for your project?
The most common types of metal used in the U.S. construction industry include copper, aluminum, stainless steel, and carbon steel. Cold formed sheet piling works best for projects such as roofing, wall construction, and steel rack construction.
