A286 UNS S66286 Iron Base PH Superalloy Forgings for Gas Turbines, Aerospace and Oil and Gas Discs, Impellers, Fasteners and Rings Jiangsu Liangyi

Product Description

Jiangsu Liangyi is an ISO 9001:2015-certified forging manufacturer in China supplying A286 / UNS S66286 (iron-base PH superalloy) open-die forgings, seamless rolled rings and bars to gas-turbine, aerospace, power and oil & gas projects in India and worldwide, to AMS 5731/5732 and ASTM A453 Grade 660 / A638 Type 660.

Why A286 / UNS S66286 for Indian gas-turbine and aerospace projects

A286 is the highest-strength iron-base precipitation-hardening superalloy ( Ni(Ti,Al)), holding 900 MPa with useful strength and creep resistance to ~704 C, non-magnetic and cryogenic-capable to -196 C, at a fraction of nickel-base-superalloy cost. For India's gas-turbine, aerospace, power and oil & gas sectors, S66286 suits turbine discs, compressor impellers, retaining rings and fastener stock.

Documented capability

Aerospace/gas turbines: turbine discs/spacers, compressor impellers, casings, retaining rings, fastener stock.

Oil & gas: downhole tools, valve/fastener forgings.

Power/nuclear: steam/gas-turbine components, reactor internal forgings, high-strength rings.

Automotive/industrial: turbocharger wheels/shafts, exhaust high-temperature fasteners.

Product range for Indian buyers

Forged bars, shafts; seamless rolled rings; turbine discs and spacers; compressor impellers; valve and retaining-ring forgings; fastener and bolting stock; nozzles, discs, hubs, sleeves.
