660 (A286) is a high-nickel stainless steel that is in common use in the Petro-chemical, Oil & Gas and Offshore Industries. It has good mechanical strength at temperatures up to 700 Deg. C, in addition to high resistance to corrosion and oxidization up to 800 Deg. C.
At Bolt King, we are adept at manufacturing 660 fasteners, and are one of the few manufacturers in the UK with the expertise to hot-forge 660 bolts and nuts on-site. Our current range for hot-forging these products is M6 - M39.
