A 286 iron-nickel-chromium based superalloy forgings

Availability:
Quantity:

A-286 alloy is an age-hardenable iron-nickel-chromium superalloy for applications requiring long-term high strength from -195°C-538°C. If short-term high strength properties are acceptable, the alloy can be used between 704-816°C. Oxidation resistance is high for continuous service to 816°C and intermittent to 982°C.

A-286 Main features and applications

It has high yield strength and endurance, creep strength below 650 ° C, as well as good processing plasticity and satisfactory welding performance.

A-286 (Ni Cr Fe) is an alloy material with high high-temperature strength and resistance to high-temperature oxidation.

Widely used in the manufacturing of components for aviation engines and industrial gas turbines, such as turbine blades

Afterburner and fasteners are also widely used in automotive engines. High temperature load-bearing components of aircraft engines that operate for a long time below 650 ° C, such as turbine discs.
