A4-80 High-Tensile Stainless Steel

 

A4-80 is a high-tensile stainless steel that is in common use in the Petro-chemical, Oil & Gas and Offshore Industries. It has great mechanical strength in addition to good resistance to corrosion. Higher mechanical strength as compared to standard A4 / 316 is achieved through the cold-drawing process, providing a minimum Ultimate Tensile Strength of 800 MPa.

At Bolt King, we are adept at manufacturing A4-80 fasteners, and are able to hot-forge A4-80 bolts and nuts on-site. By using cold-worked raw material with tensile strengths in excess of 1000 MPa, we can retain the A4-80 properties even after the forging process.  Our current range for hot-forging these products is M6 - M48.

If you have any questions or queries with regard to A4-80 bolting, please contact us.
