Stainless Steel 17-4 Condition HH1150 is 17-4 material that has been heat treated twice at a temperature with a range between 1140F and 1160F for a length of time of 225-255 minutes. This material will become softer than it is in the annealed condition after it is heat treated at such a high temperature.
