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

AMS 5659 Specification & 15-5PH Steel
15-5PH stainless is a highly corrosion-resistant stainless steel containing approximately 15% chromium and 5% nickel. Common AMS 5659 specifications include:
- AMS 5659 TYPE 1
- ASTM-A484
- ASTM-A564
- ASME-SA564
AMS 5659 is further differentiated by the type of heat treatment used to form it. The three types of treatment include vacuum arc remelt (Type 1), electric slag remelt (Type 2), and hot rolled anneal. Heat treatment hardens steel and adds to its tensile strength.
