A-286 (GH2132)
Iron-nickel-chromium precipitation-hardening superalloy for high strength to about 700 C.
Material overview
The High-Temperature Superalloys catalog describes A-286 (GH2132) as follows: Iron-nickel-chromium precipitation-hardening superalloy for high strength to about 700 C. Reviewers should evaluate Age hardens via gamma-prime, high tensile and creep strength, and good oxidation resistance. The grade record lists Gas-turbine discs and wheels, fasteners, supercharger parts, industrial turbines, and oil and gas components among typical applications. The dataset currently includes 15 property records covering chemical composition, mechanical properties, and physical properties. Standards and form records reference B637 and GB/T 14992 and Bar / Rod and Forged Product. Final supply conditions remain subject to specification, inspection, and export-control review.
