Introduction to 17-7PH Stainless Steel Material
17-7PH is a stainless steel alloy with high strength, good elasticity, and corrosion resistance. Composed of iron, chromium, nickel, aluminum, and molybdenum with small amounts of carbon, copper, and silicon, this alloy offers excellent tensile properties, elastic recovery ability, and stability in high temperature and corrosive environments.
Chemical Composition
| C | Cr | Ni | Mn | Si | P | S | Al |
|---|---|---|---|---|---|---|---|
| ≤0.09% | 16.00-18.00% | 6.50-7.75% | ≤1.00% | ≤1.00% | ≤0.040% | ≤0.030% | 0.75-1.50% |
- Carbon (C): Below 0.09% to improve hardness and strength
- Chromium (Cr): 16.00-18.00% for enhanced corrosion resistance
- Nickel (Ni): 6.50-7.75% working with chromium for corrosion resistance
- Manganese (Mn): Below 1.00% to improve strength and hardness
- Aluminum (Al): 0.75-1.50% to enhance strength and hardness
