Rupal Metals from Delhi, India, is a reliable manufacturer and supplier of top-quality Stainless Steel 17-4PH Forgings. They are known for accuracy and reliability, providing higher-grade forging solutions that surpass strict industrial standards. Rupal Metals’ 17-4PH Forgings are produced using advanced methods, ensuring high strength and resistance to corrosion, suitable for demanding applications. With the dedication towards quality and timely delivery, Rupal Metals caters to various sectors like aerospace, chemical, and petrochemical industries and is a choice of preference for a reliable stainless steel forging product in India.
Stainless Steel 17-4PH Forgings are essentially made up of iron with about 16-17.5% chromium, 3-5% nickel, 3-5% copper, and traces of manganese, silicon, and niobium. This precipitation-strengthening stainless steel has good mechanical properties like high tensile strength, yield strength of up to 1100 MPa, and good hardness after heat treatment. It provides excellent corrosion resistance, particularly against stress corrosion cracking, and good toughness and weldability, and therefore can be applied for applications demanding strength and resistance to hostile environments.
