Stainless Steel Grade 17-4 UNS S17400

Stainless Steel Grade 17-4 UNS S17400 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, during  aging treatment, on the martensitic matrix can be the second phase  precipitation and make the steel reinforcement. The role of Al is to form a  sedimentation hardening phase for other elements (Ni3Al). In the aging process,  the cooling is not urgent, otherwise it is difficult to achieve the  reinforcement effect.
