Reputable manufacturer and supplier Neil Metals, located in Kolkata, India, is well-known for providing premium stainless steel 347 hex bars and rods that are made to exacting industrial specifications. Stabilised austenitic stainless steel grade SS 347, which contains columbium (niobium), provides remarkable resistance to high temperatures and intergranular corrosion. Our precision-engineered 347 hex bars and rods have outstanding surface finish and dimensional accuracy. These bars are extensively utilised in sectors like petrochemicals, power generation, and aerospace because they are perfect for welding and high-heat applications. In both domestic and international markets, Neil Metals guarantees constant product quality, prompt delivery, and total customer satisfaction.
Stainless Steel 347 Hex Bars/Rods are stabilised with niobium (columbium), which stops the precipitation of chromium carbide, and normally contain 17–19% chromium and 9–13% nickel. Particularly after welding, this alloy shows outstanding resistance to intergranular corrosion. It has good elongation and toughness at high temperatures, with a tensile strength of about 515 MPa and a yield strength of about 205 MPa. 347 stainless steel is perfect for high-pressure and heavy thermal cycling applications because it is non-magnetic when annealed and can retain structural integrity in hot conditions.

347 Stainless Steel In many different industries, hex bars and rods are widely used in high-temperature and high-stress applications. They are used in engine parts and exhaust manifolds in the aerospace industry. They are used in furnace parts, reactors, and heat exchangers in the chemical and petrochemical industries. SS 347 is perfect for welded pressure vessels and piping systems because of its resistance to intergranular corrosion following welding. Additionally, it is used in marine, pharmaceutical, and food processing settings where resistance to corrosion and temperature are critical. In mechanical constructions and precision assemblies, the hexagonal shape guarantees strength and usability.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
