15-5 PH, also known as also known as UNS S15500 or XM-12. is a martensitic, precipitation-hardening stainless steel. Popular due to its high strength and good corrosion resistance, 15-5 PH also offers users a host of other benefits:
- Good mechanical properties at temperatures up to 600°F (316°C)
- Excellent longitudinal and transverse toughness
- Good in corrosive and high-pressure environments
- Equivalent weldability to 17-4 PH with greater toughness
- Low temperature hardening
Because of these outstanding characteristics, 15-5 PH is used to create gears, shafts, fittings, valves, cylinders, engine parts, and fasteners for a wide range of industries including:
- Aerospace
- Petrochemical
- Chemical
- Food Processing
- Pulp and Paper
In order to be sold as 15-5 PH stainless steel, an alloy must have a certain composition that includes:
