17-4PH alloy is a precipitation, hardening, martensitic stainless steel composed of copper, niobium/columb.

This grade has high strength, hardness (up to 300º C/572º F) and corrosion resistance.

After heat treatment, the mechanical properties of the product are more perfect, and can reach a compressive strength of up to 1100-1300 mpa (160-190 ksi).

It cannot be used at temperatures higher than 300º C (572º F) or very low temperatures. It has good corrosion resistance to the atmosphere and diluted acids or salts. Its corrosion resistance is the same as 304 and 430.
