THIS stainless steel is Used as a spring, hot meter components, Half austenitic precipitation-hardening stainless steel, is a kind of unstable austenitic stainless steel, the steel solid solution state, at room temperature for austenitic organization, after cold working, cold treatment, or heated to 750 degrees to adjust processing, austenite transformation martensite, then aging treatment, the second phase precipitation on the martensitic matrix can be and make the steel reinforcement.Al's role is as and other elements to form heavy play hardening phase such as (Ni3Al).In the process of aging, the cooling is not flash, it's hard to strengthen effect
2.Product Application Areas:
Our products have been used in all kinds of areas, such as aviation,aerospace,navigation,nuclear energy,chemical industry,
electronic information,achine manufacture, petrochemical, automotive,instrument and meter, Communication ,transportation, and medical instruments, etc.
