17-4PH Stainless Steel (H1150 Condition)
17-4PH (H1150): Precipitation Hardening for High-Stress Ductility. Heat-treated for optimized toughness and stress-corrosion resistance.
17-4PH Stainless Steel (H1150 Condition)
17-4PH is a chromium-copper precipitation-hardening stainless steel. In the H1150 condition (over-aged), the material is treated to achieve a specific balance of high strength and improved ductility, making it less susceptible to hydrogen embrittlement than higher-strength tempers.
