In this article, we’ll break down what makes stainless steel so special (yes, including a handy composition table), plus introduce you to the premium stainless steel products we offer at Don-Tek Steel.

What Exactly Is Stainless Steel?
Stainless steel is like the superhero of metals—strong, shiny, and corrosion-resistant. It's made by mixing iron with elements like chromium, nickel, and sometimes molybdenum or manganese. The result? A tough, rust-resistant alloy that’s perfect for everything from kitchen sinks to skyscrapers.

Let’s Talk Composition
Here’s a quick look at the basic ingredients that go into popular stainless steel grades:

The three common grades of stainless steel are 304, 316 and 430.

The 304 grade has a chromium content of between 18% and 20%, a nickel content of between 8% and 10.5%, and a low carbon content of no more than 0.08%. With excellent corrosion resistance and versatility, this stainless steel is one of the most widely used.

The 316 grade is a step up. It has a chromium content of 16 to 18 percent, a higher nickel content of 10 to 14 percent, and 2 to 3 percent molybdenum. Molybdenum makes 316 more resistant to harsh chemicals and salt water, making it ideal for marine or industrial use. Like 304, it has an upper carbon limit of 0.08 percent.

On the other hand, 430 is a more affordable option. It contains 16 to 18 percent chromium, but no added nickel or molybdenum. Its carbon content is slightly higher, up to 0.12 percent, but it is still a low carbon product. This grade is typically used in less demanding environments, such as kitchen equipment or decorative applications.

Each grade has its own personality. For example, 304 is your all-around MVP, while 316 steps up in harsh environments like marine or chemical settings.
