Dhruv Metals, located in Hyderabad, India, has earned a solid reputation as a reliable manufacturer and supplier of high-quality Stainless Steel 321 Hex Bars and Rods. They cater to industries that require exceptional corrosion resistance and outstanding performance at high temperatures. Known for their commitment to meeting global standards, Dhruv Metals produces 321 hex bars and rods that boast remarkable durability and stability during thermal cycling. Thanks to their advanced manufacturing techniques, skilled workforce, and thorough quality control, every product they offer is designed to deliver dependable performance, making them a go-to choice for sectors like aerospace, petrochemical, and heat treatment.
The Stainless Steel 321 Hex Bars and Rods are crafted from a titanium-stabilized austenitic stainless steel, which contains around 17-19% chromium, 9-12% nickel, and titanium added at a level five times that of the carbon content. This stabilization process effectively prevents carbide precipitation, providing excellent resistance to intergranular corrosion even after exposure to high temperatures. These hex bars and rods exhibit a tensile strength of approximately 515 MPa, a yield strength of 205 MPa, and an elongation of about 40%. They maintain their strength and oxidation resistance up to 900°C while also offering good formability and weldability.

SS 321 hex bars/rods are highly suitable for high-temperature applications due to their excellent resistance to oxidation and scaling, particularly in environments above 900°C. The addition of titanium stabilizes the material, preventing carbide precipitation, and enhancing its resistance to intergranular corrosion, making it ideal for aerospace and industrial applications.
SS 321 hex bars/rods are commonly used in industries requiring high-temperature resistance, such as aerospace, chemical processing, and power generation. Applications include exhaust systems, heat exchangers, furnace components, and reactors. Their resistance to corrosion, oxidation, and scaling makes them ideal for environments with elevated temperatures and aggressive conditions.
SS 321 hex bars/rods can be welded easily, but special care is needed to prevent carbide precipitation. Preheating and post-weld heat treatment are recommended to avoid weld embrittlement. Using titanium-stabilized filler metals helps maintain the alloy’s resistance to intergranular corrosion, ensuring weld integrity in high-temperature applications.
Stainless Steel 321 Hex Bars and Rods find their place in applications that demand high strength, good creep resistance, and resistance to intergranular corrosion at elevated temperatures. You’ll commonly see them used in aircraft exhaust manifolds, expansion joints, furnace components, thermal processing equipment, and heat exchangers. They’re also utilized in petrochemical and refinery piping, welded pressure vessels, and flue gas systems. Their hexagonal shape is perfect for creating fasteners, fittings, and precision-machined parts. The stabilized composition of SS 321 ensures reliability for components that undergo repeated heating and cooling, guaranteeing durability and structural integrity even in the toughest service conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
