15-5PH powder applications by industry
| Industry | Typical parts | Why 15-5PH | Specify in your RFQ |
|---|---|---|---|
| Aerospace structures | Fittings, brackets, actuator parts | Precipitation-hardening stainless with better transverse toughness than 17-4PH | Heat-treatment condition, governing specification, test coupons |
| Valves and pumps | Stems, bodies and brackets needing strength and moderate corrosion resistance | High strength stainless with good toughness | Media, pressure, final condition |
| Tooling and fixtures | Strong stainless jigs and fixtures | Hardenable stainless for repeated mechanical use | Hardness, wear surfaces, datums |
Designations
- 15-5PH
- UNS S15500
- XM-12
- EN 1.4545
Use 15-5PH, UNS S15500, XM-12, or EN 1.4545 in international RFQs and state the aging condition you will qualify, because 15-5PH and 17-4PH differ in ferrite control and toughness.
