Dhruv Metals, located in Hyderabad, India, has built a solid reputation as a manufacturer and supplier of Stainless Steel 321 Round Bars and Rods. These products are celebrated for their outstanding performance in high-temperature and corrosive settings. Stainless Steel 321 is an austenitic stainless steel that’s stabilized with titanium, which helps prevent carbide precipitation during welding and exposure to high heat. This makes SS 321 a fantastic choice for applications that demand excellent corrosion resistance, strength, and thermal stability. At Dhruv Metals, we pride ourselves on precision manufacturing and quality assurance, providing SS 321 round bars and rods to a diverse array of industries, including aerospace, chemical, and power generation.
The composition of Stainless Steel 321 Round Bars and Rods includes chromium (17.0–19.0%), nickel (9.0–12.0%), carbon (≤0.08%), and titanium (at least five times the carbon content), along with carefully controlled amounts of manganese, silicon, phosphorus, and sulfur. These bars boast a minimum tensile strength of 515 MPa, a yield strength of 205 MPa, an elongation of 40%, and a maximum Brinell hardness of 217 HB. The titanium stabilization not only enhances resistance to intergranular corrosion but also helps maintain mechanical strength at elevated temperatures.

Yes, Stainless Steel 321 Round Bars and Rods can be used for underground applications. Their excellent corrosion resistance, especially in high-temperature and acidic environments, makes them suitable for underground pipelines and structures.
Stainless Steel 321 Round Bars and Rods find their place in industries where heat and corrosion resistance are paramount. Common applications include exhaust systems, heat exchangers, expansion joints, furnace components, and chemical processing equipment. SS 321 is particularly advantageous in welded structures that experience temperatures between 427°C and 816°C. Its ability to resist scaling and maintain strength under thermal cycling conditions makes it a go-to material in the aerospace, refinery, and thermal processing sectors, where long-lasting durability 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.
