Product introduction
17-4PH is a martensitic precipitation hardening stainless steel. After heat treatment, the mechanical properties of the product are improved, and the compressive strength can reach 1100-1300 Mpa (160-190 ksi). This grade can not be used at temperatures higher than 300 (572) or very low. It has good corrosion resistance to atmosphere and diluted acid or salt.
17-4ph stainless steel performance characteristics:
It is easy to adjust the strength grade, which can be adjusted by changing the heat treatment process. The precipitation hardening phase formed by martensitic transformation and aging treatment is the main strengthening method.
17-4PH has good attenuation, corrosion fatigue resistance and water drop resistance.
17-4ph stainless steel bar application:
1. Offshore platforms, helicopter decks, other platforms
2. Food industry
3. Pulp and paper industry
4. Aerospace (Turbine Blades)
5. Mechanical components
6. Nuclear Waste Bucket
