Austenitic Stainless Steel

Austenitic stainless steel is by far the most common material used to manufacture stainless steel fasteners. It has a chromium content between 15 and 20 percent and a nickel content between 5 and 19 percent. It offers the highest corrosion resistance than martensitic stainless steel and ferritic stainless steel. It is also considered to be non-magnetic. The tensile strength may vary between 72,000 psi and 115,000 psi. Austenitic stainless steel is not heat treatable however the strength of this material may be improved by cold working or strain hardening.


The material that is commonly referred to as 18-8, is a type of austenitic stainless steel that contains approximately 18% chromium and 8% nickel. Austenitic stainless steel includes AISI grades 302, 303, 304, 304L, 316, 32, 347, & 348.
