Fastener Materials: A Closer Look at Stainless Steel

Should I use Stainless Steel for fastening in my next project? That’s a good question. Fasteners come in a variety of materials and it is important to consider your project before you decide what material to use for it.

Many fastening options involve steel. The main options you have for steel are Low Carbon Steel, Medium Carbon Steel, Alloy Steel, Stainless Steel, or Austenitic Stainless Steel. Let’s take a closer look at Stainless Steel.

Stainless Steel
Stainless steel is made up of alloy steels that contain a minimum of 10.5% chromium content. The presence of chromium creates an invisible surface film that resists oxidation and makes the metal corrosion resistant. If the surface is damaged, it rebuilds itself in the presence of oxygen. It is important to understand the self-healing process because stainless steel used in a low oxygen surrounding is susceptible to aggressive influences if the protective surface layer becomes damaged.

Stainless steel is divided into three classes: Austenitic, Martensitic and Ferritic.

Stainless Steel fasteners are a good option when you need a fastener with high corrosion resistance because these fasteners will not easily deteriorate.
