About Stainless Steel
Compare over 25 types of stainless steel to find the right material for you—all with material certificates for traceability.
Hardened High-Strength 17-4 PH Stainless Steel
This material is hardened for improved strength and wear resistance. With a higher chromium content than 15-5 PH stainless steel, this high-strength 17-4 PH offers better corrosion resistance. It is also known as 630 stainless steel. This material maintains its corrosion resistance in temperatures up to 1100° F.
