17-4ph Metal Powder Injection Molded Parts

Product Description

17-4PH is a martensitic precipitation hardening stainless steel. The characteristic of 17-4PH is that it is easy to adjust the strength level, which can be adjusted by changing the heat treatment process. The precipitation hardening phase formed by martensitic phase transformation and aging treatment is the main strengthening method. 17-4PH has good attenuation performance, strong anti-corrosion fatigue and anti-water drop performance.

Application field

• Offshore platforms, helidecks, other platforms

• Food industry

• Pulp and paper industry

• Aerospace (turbine blades)

• Mechanical components
