These Stainless Steel UNS S32100 Fasteners are made from high-quality raw resources and are
suitable for a wide range of industrial and commercial applications. These SS 321H
Fasteners are available in a variety of finishes and sizes and are highly
valued for their corrosion resistance and dimensional perfection.
One of the motivations for the creation of the 321 grade of stainless steel was its remarkable
resistance to intergranular corrosion when subjected to temperatures ranging from 427° C to 816°
C during chromium precipitation. The inclusion of titanium in the alloy of 321 Stainless Steel
Fasteners is what keeps it stable against chromium carbide formation.
