What is 17-4 PH Stainless Steel?

17-4 PH stainless steel, also known as UNS S17400 or Grade 630, is a chromium-nickel-copper precipitation hardening martensitic stainless steel.

It provides an excellent combination of:

High tensile strength

Excellent hardness

Superior corrosion resistance

Good fatigue strength

Excellent mechanical properties

Heat treatment capability

It is widely used in industries where both corrosion resistance and high strength are essential.
