Stainless Steel 17-4 H1150 is a chromium copper precipitation hardening stainless steel that is used for applications that requires high strength and a moderate level of corrosion resistance. Alloy 17-4 is one of the most widely used grades that is precipitated hardening.
Stainless Steel 17-4 H1150 is heat treated at a temperature between 1140F and 1160F for a period of time of 225-255 minutes. The steel becomes softer that it is in its annealed condition after being treated at this high temperature.
