15-5 ph Stainless Steel Bar
15-5 is a variant of the older 17-4 chromium-nickel-copper precipitation hardening stainless steel. Both alloys exhibit high strength and moderate corrosion resistance. High strength is maintained to approximately 600 degrees F. The 15-5 alloy was designed to have greater toughness than 17-4. This improved toughness is achieved by reduced delta ferrite content and control of inclusion size and shape.
Applications:
- Aircraft components
- High pressure corrosive fabricated parts such as valves
- Shafts
- Fasteners
- Fittings and gears
