Stainless Steel 347/347H Round Bar

SS 347 Round Bar is a stabilized austenitic stainless steel product designed for applications requiring high strength and resistance to oxidation and corrosion at elevated temperatures. These round bars are widely used in industries such as chemical processing, petrochemical plants, power generation, and aerospace components due to their durability and reliable mechanical performance. Sumit Impex, a trusted manufacturer and supplier in Mumbai, India, provides high-quality Stainless Steel 347 Round Bars that are produced with advanced manufacturing techniques to ensure consistent quality and long service life in demanding industrial environments.

The SS 347 Round Bar is manufactured from stainless steel grade UNS S34700 / EN 1.4550, which contains chromium, nickel, and niobium for improved stability and corrosion resistance. The addition of niobium helps prevent intergranular corrosion and enhances performance when exposed to high temperatures. Because of these properties, 347 Stainless Steel Round Bars are commonly used in welded equipment, heat exchangers, and refinery components where materials are exposed to thermal stress and corrosive conditions.

The SS 347H Round Bar is a higher-carbon variation of grade 347, identified by UNS S34709 / EN 1.4961, which provides improved strength and better creep resistance at elevated temperatures. This makes Stainless Steel 347H Round Bars particularly suitable for high-temperature service applications such as boilers, pressure vessels, and heat-resistant structural components. Due to its enhanced mechanical properties and oxidation resistance, 347H Stainless Steel Round Bar is widely used in industries where materials must withstand continuous exposure to heat and pressure.
