SSF started off producing Stainless Steel bolting in its formative years, and although the company has since diversified into more exotic materials, we continue to offer Stainless Steels and they continue to be an important part of our business, especially if customers require non-standard bolting: i.e. non-standard sizes, special specification, or otherwise difficult to find. We offer all grades of stainless steels, be it Austenitic, Ferritic or Martensitic.

Other materials

SSF manufactures other super alloys and special materials upon request. For example we have gained vast experience producing 17-4PH bolts, 904L bolts, and 254 SMO bolts.

Other material groups:

Duplex
Super Duplex
High Nickel Alloys
Titanium
