Product Description

Jiangsu Liangyi is an ISO 9001:2015-certified forging manufacturer in China supplying ASTM A453 Grade 660 / UNS S66286 (A286 bolting) forgings, fastener stock and bars to gas-turbine, pressure-vessel, power and oil & gas projects in India and worldwide, to ASTM A453 classes A/B/C/D and AMS 5731/5732.

Why ASTM A453 Grade 660 for Indian bolting and fastener projects

Grade 660 is the A453 bolting specification for the A286 iron-base PH superalloy 895 MPa tensile, preload and stress-rupture strength to 700 C, non-magnetic, with thermal expansion matched to austenitic flanges. For India's gas-turbine, pressure-vessel, power and oil & gas sectors, S66286 suits stud-bolt and threaded-rod stock, valve-flange bolting, fastener blanks and rings.

Documented capability

Gas turbines/aerospace: engine/turbine bolting stock, casing fasteners, stud-bolt/threaded-rod blanks.

Pressure vessels/valve flanges: high-temperature valve-flange and vessel bolting, studs, nuts, washers stock.

Power/nuclear: boiler/super-heater/turbine bolting, reactor fastener and ring forgings.

Oil & gas/automotive/exhaust: downhole/subsea bolting, turbocharger waste-gate and exhaust fasteners.
