15-5PH / UNS S15500 Stainless Steel Round Bar Black or Bright Finish
-
15-5PH Precipitation hardening stainless steel alloy (S15500) is a variant of the older 17-4 PH (S17400) chromium-nickel-copper precipitation hardening stainless steel both alloys exhibit high strength and moderate corrosion resistance
-
High strength is maintained to approximately 600°F (316°C)
-
The 15-5 PH alloy was designed to have greater toughness than 17-4 PH, especially in the through-thickness (short transverse) direction
-
This improved toughness is achieved by reduced delta ferrite content and control of inclusion size and shape
-
