was rapidly cooled after heating at 980-1000°C. |
|
precipitation hardening treatment |
heating to 700°C and holding for several hours to improve tensile strength and fatigue resistance. |
machining and welding
·Cold working: suitable for cold drawing and cold rolling, which can improve strength.
·hot processing: at about 980°C, to avoid high temperature lead to coarse grains.
·welding: through argon arc welding, electron beam welding and other welding methods, after welding, heat treatment to restore mechanical properties.
Application
·Aerospace: used for turbine engine blades, nozzles, etc.
·turbine components: turbine disks and blades.
·Petrochemical industry: suitable for refining equipment, valves and pipelines.
·Fasteners and springs: Fasteners and springs in high temperature environments.
A286 alloy is available in different shapes and sizes, including plate, bar, wire and forgings.
