Rupal Metals is a reliable Delhi, India-based manufacturer and supplier of high-quality Stainless Steel 347 Round Bars and Rods. Having exceptional durability and corrosion resistance, the bars and rods are capable of meeting tough requirements of many different industries. Utilizing cutting-edge production methods and rigorous quality control, Rupal Metals provides products which are up to international standards. Their Stainless Steel 347 Round Bars and Rods are suitable for high-temperature applications and are a highly sought-after product among clients in industries such as chemical processing, aerospace, and power generation for durable performance and extended usage.
Stainless Steel 347 Round Bars and Rods consist mainly of chromium (17–19%), nickel (9–13%), and columbium (niobium) stabilizes the alloy against intergranular corrosion. This austenitic stainless steel has very good resistance to oxidation at high temperature and creep. Its mechanical features consist of tensile strength around 515 MPa, yield strength of 205 MPa, elongation of 40%, and a Brinell hardness of about 217 HB. These features make it the best material to utilize in high-temperature conditions where structural integrity and resistance to corrosion are important.
