Stainless steel 17-4PH is a precipitation hardening stainless steel with excellent mechanical properties.

High Mechanical Properties: With proper heat treatment, 17-4PH stainless steel can achieve very high tensile and yield strengths while maintaining good ductility.

Good corrosion resistance: The high chromium content gives it good corrosion resistance, especially in seawater, chlorides and other corrosive environments.

Machinability: 17-4PH stainless steel can be machined by conventional machining methods such as cutting, drilling and grinding.
