Stainless Steel 17-4 PH

Stainless Steel 17-4 PH

17-4 PH steel is a grade of martensitic, precipitation-hardening stainless steel with the additions of chromium, nickel, and copper. 17-4 stainless steel is capable of attaining a wide range of strength and toughness properties depending on the precipitation or aging temperature used in hardening. It has a valuable combination of high strength, good corrosion resistance, and toughness in both base metals and welds. These properties give designers the ability to add reliability to their products while simplifying fabrication and often reducing their costs. High strength is maintained to approximately 600°F (316°C). This material has good resistance to stress corrosion cracking in the low strength conditions.

Application Industries

These materials are not a single material but the name for a family of corrosion resistant steels. Like many scientific breakthroughs, the origins of stainless steel lies in a lucky accident. From the smallest part of the zipper to the largest building skyscraper.
Metal fabrication is widely used across various industrial sectors such as mining, construction, manufacturing, shipbuilding, automotive, aerospace, and energy.
