| PRODUCT DATA of 15-5PH H900 |
| Material | 15-5PH H900 |
| General Information | 15-5PH is a precipitation-hardening, martensitic stainless steel used for parts requiring corrosion resistance and high strength at temperatures up to 315C. Alloy 15-5PH has good transverse ductility and strength in large section sizes. This material is supplied in either the annealed or overaged condition and is heat treated after fabrication |
| Processing and Assembly | cold worked and aged at 480C |
| Precautions | Parts should never be used in annealed condition. |
