17-4 Ph Round Bar is a grade of martensitic, precipitation-hardening stainless steel with the additions of chromium, nickel, and copper. It is the widely used amongst all the precipitation hardening stainless steel. 17-4 Ph Stainless Steel Round Bar has a valuable combination of high strength, good corrosion resistance, and toughness in both base metals and welds. It can be welded using common fusion and resistance welding methods. For welding this alloy oxyacetylene welding method is not preferred.
