Product introduction
17-7ph (ASTM 631) is a Semi-austenitic precipitation hardening stainless steel, which is an austenitic unstable stainless steel. 17-7ph steel is solid solution and austenite structure at room temperature. After cold processing, cold treatment or heating to about 750 degrees, the austenite can transform martensite. Aging treatment can precipitate the second phase on the basis of martensite and strengthen the steel.
17-7ph stainless steel bar mechanical properties:
Tensile strength σb (MPa)：solution≤1030; 565℃ aging≥1140; 510℃ aging≥1230
Yield strength σ0.2 (MPa)：solution≤380; 565℃ aging≥960; 510℃ aging≥1030
Elongation δ5 (%)：solution,≥20;565℃ aging≥5; 510℃ aging≥4
