17-7PH AMS 5529 Stainless Steel Sheet 

17-7PH stainless steel plate is a precipitation hardening stainless steel. After cold working and heat treatment, its tensile strength and yield strength are much higher than 304 and 316 steels, and even higher than 17-4PH. Although its corrosion resistance is slightly lower than that of austenitic 304 stainless steel, 17-7PH stainless steel plate still performs well in most industrial and atmospheric environments, and its high hardness and low deformation help to extend its service life. After TH 1050 or CH 900 heat treatment, it can obtain high strength and maintain excellent dimensional stability, which is suitable for parts with high precision requirements.
17-7PH stainless steel cold rolled plate can be processed by cold rolling, shearing, stamping, etc., and heat treatment after processing can obtain the final required strength. Suitable for manufacturing high-strength parts with complex shapes.
