Stainless Steel PH 17-7 Material Round Bar Ø260 ASTM S17700 AISI631,SAE17-7PH Forge Rod
17-7 PH is a chromium-nickel-aluminum precipitation hardening stainless steel that provides high strength and hardness and a moderate level of corrosion resistance up to 600˚F. This grade can be easily formed in the austenitic condition similar to Type 301 stainless steel and hardened to high strength levels using relatively low heat treatments that minimize distortion. The corrosion resistance of 17-7 PH is comparable to that of Type 304 stainless steel, especially in the CH 900 temper, and it has been used for spring applications, washers, eyelets, fittings and fasteners.
Heat treatments can strengthen this type of stainless steel. The typical process for 17-7 PH heat treatment has three or four steps:
| Element | Content(%) |
|---|---|
| Chromium, Cr | 16-18 |
| Nickel, Ni | 6.50 – 7.75 |
| Manganese, Mn | 1 max |
| Silicon, Si | 1 max |
| Aluminum, Al | 0.75 – 1.50 |
| Carbon, C | 0.09 max |
| Phosphorous, P | 0.040 max |
| Sulfur, S | 0.030 max |
| Iron, Fe | balance |
