Fastener Materials: A Closer Look at Austenitic Stainless Steel

When picking the fastener for your next project, you are going to want to consider the material it is made of. Many of our options include steel fasteners. The main options you have for steel are Low Carbon Steel, Medium Carbon Steel, Alloy Steel, Stainless Steel, or Austenitic Stainless Steel.

Stainless Steel
Stainless Steel is an alloy that combines carbon grades with chromium and nickel. To be Stainless Steel, the alloy must contain at least 10.5% chromium. Austenitic is a type of Stainless Steel. Let’s take a closer look at Austenitic Stainless Steel.

Austenitic Stainless Steel
Austenitic stainless steel has a chromium content between 15% and 20% and a nickel content between 5% and 19% and offers a higher degree of corrosion resistance than the other two types of stainless. The tensile strength of austenitic stainless steel varies between 72,000 psi and 115,000 psi (500 MPa to 800 MPa). 18-8 stainless steel is a type of austenitic stainless that contains approximately 18% chromium and 8% nickel. This group includes AISI grades 302, 303, 304, 304L, and 316.

Consider using Austenitic Stainless Steel in projects that need corrosion resistance or projects that involve exposure to high heat. Do you still have questions about fastener materials?
