SUS 633 precipitation hardening stainless steel AM-350, S35000

SUS633 (AM-350, S35000) precipitation hardening stainless steel overview:

633 stainless steel is AM-350 stainless steel, American semi-austenitic precipitation hardening stainless steel. In 1954 the United States Allegheng Ludlum (Allegheng Ludlum) company supply. Semi-austenitic precipitation-hardening stainless steel has unique advantages: after solution, it has the advantages of austenitic steel, and is easy to cold-form; after the strengthening treatment, it has the advantages of martensitic steel, and the heat treatment temperature is not high. Defects of deformation and oxidation. However, when this kind of steel is used for a long time at a temperature of 315 ° C or higher, the intermetallic compound continues to precipitate and the material becomes brittle, so the use temperature is limited to 315 ° C or lower.
