Dhruv Metals, a prominent manufacturer and supplier located in Hyderabad, India, specializes in high-quality Stainless Steel 347 Hex Bars tailored for demanding industrial applications. Renowned for their precision-engineered products, Dhruv Metals provides 347 Hex Bars that excel in resisting intergranular corrosion, even after welding and exposure to high temperatures. These bars are perfect for challenging environments like chemical processing, heat treatment, and power generation. With a strong focus on quality, durability, and customer satisfaction, Dhruv Metals serves both domestic and international markets, offering customized solutions and timely delivery.
The Stainless Steel 347 Hex Bars are made up of 17–20% chromium, 9–13% nickel, and niobium (columbium) for stabilization, which boosts their resistance to intergranular corrosion. This austenitic stainless steel boasts a tensile strength of about 515–750 MPa, a yield strength of around 205 MPa, and an elongation of 35%. It retains excellent mechanical properties at elevated temperatures and is resistant to oxidation and scaling. The hexagonal shape not only enhances torque but also provides structural strength, making these bars ideal for machining and structural applications that require both durability and corrosion resistance in high-temperature settings.

SS 347 Hex Bars are widely used in aerospace, chemical processing, and power generation for applications requiring high-temperature resistance, corrosion resistance, and strength. They outperform other grades due to their niobium stabilization, preventing carbide precipitation and ensuring durability.
SS 347 Hex Bars typically exhibit a tensile strength of 515-750 MPa, a yield strength of 205 MPa, and an elongation of 40% minimum. These properties ensure high durability, flexibility, and performance in demanding applications.
SS 347 Hex Bars commonly comply with standards like ASTM A276, ASTM A479, ASME SA479, and AMS 5646. These certifications ensure quality, dimensional accuracy, and performance for high-temperature and corrosion-resistant applications across industries, meeting stringent safety and reliability requirements.
Stainless Steel 347 Hex Bars find extensive use in industries that demand robust performance under high temperatures and corrosive conditions. Common applications include heat exchangers, boiler tubes, radiant superheaters, and exhaust manifolds in power plants and refineries. They are also employed in chemical processing equipment, expansion joints, aerospace components, and welded structures that face high stress and thermal cycling. The alloy’s stabilization with niobium makes it particularly effective at resisting intergranular corrosion after welding, making it a top choice for welded assemblies. These hex bars are favored in environments where long-term strength and stability are crucial.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
