We produce screws, stud bolts and nuts ASTM A453 GR 660, Alloy 286, 1.4980 material.It is a precipitation hardening steel heat resistant, recommended in case of high mechanical resistance and corrosion resistance up to 700°C.  It is suitable to be used in jet engines, turbines, gears, paddles, nuts, bolts, spring washers and other devices that require high temperatures resistance.
The corrosion resistance of ASTM A453 GR 660 - ASTM A286 GR 660 is excellent up to 700°C. The  oxidation resistance is good up to 800°C in current “on-order” conditions and up to 980°C in fitful “on-order” conditions.

ASTM A453 GR 660 - ASTM A286 GR 660 can be protected arc welded or arc welded in inert atmosphere. We recommend  soluble not aged condition. Soluble operation up to 980°C  lasting 1 hour and rapid cooling (by air or by water). Precipitation aging at 720°C lasting 16 hours. Forging gap 1150°C up to 1050°C avoiding to go down 930°C. The warping resistance is higher than the austenitic steels one.
