Stainless Steel Bar By Sagar Steel Centre

Stainless Steel Bar Stock 17-4 stainless steel bar, also known as UNS S17400, 17-4 PH and Grade 630, is one of the original precipitation hardened grades developed in the 50's. Primarily comprised of 17% chromium, 4% nickel, 4% copper, with the balance being iron. There are also trace amounts of manganese, phosphorus, sulfur, silicon, columbium (or niobium) and tantalum. Stainless Steel 17-4 PH delivers an excellent combination of oxidation and corrosion resistance. Other characteristics include high strength, toughness, and quality mechanical properties at temperatures up to 600 F. Engineers and designers frequently choose Stainless Steel 17-4 PH due to its high strength and superior corrosion resistance when compared to many other stainless steels. Stainless Steel 17-4 PH can be forged, welded and formed. Machining may be formed in the solution-annealed state, or in the final heat treat condition. Desired mechanical properties such as ductility and strength can be achieved through heating the material at various temperatures.
