Dhruv Metals, based in Hyderabad, India, has earned a solid reputation as a reliable manufacturer and supplier of Stainless Steel 321 Rectangular Bars. These bars are celebrated for their impressive strength, outstanding resistance to corrosion, and stability even at high temperatures. Stainless Steel 321 is an austenitic stainless steel that’s been stabilized with titanium, making it a perfect choice for welded structures and environments that experience high heat. At Dhruv Metals, we take pride in producing our SS 321 rectangular bars to exact specifications, ensuring they meet international quality standards. Our products cater to various industries, including aerospace, chemical processing, and thermal equipment manufacturing, all while delivering consistent performance and a long lifespan.
The composition of Stainless Steel 321 Rectangular Bars 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 Brinell hardness of up to 217 HB. The addition of titanium helps prevent carbide precipitation during welding, which in turn maintains the material’s corrosion resistance and structural integrity when exposed to thermal stress.

Yes, Stainless Steel 321 Rectangular Bars can be welded. They offer good weldability, particularly with proper preheat and post-weld heat treatment to prevent carbide precipitation.
Stainless Steel 321 Rectangular Bars generally do not require additional corrosion protection coatings due to their inherent corrosion resistance. However, in harsh environments, extra coatings may be applied for enhanced protection.
Choose Stainless Steel 321 Rectangular Bars based on factors like strength, corrosion resistance, and temperature requirements of your application. Consider factors like weldability and environment exposure to ensure optimal performance.
Stainless Steel 321 Rectangular Bars are commonly utilized in environments that experience high temperatures and corrosive conditions. Typical applications include heat exchangers, exhaust systems, furnace components, expansion joints, and equipment used in chemical processing. These bars are particularly well-suited for parts that face continuous or intermittent heat up to 900°C, making them especially valuable in applications that involve welding and thermal cycling. With their combination of strength, durability, and excellent weldability, SS 321 rectangular bars are ideal for structural and mechanical applications in industries that demand both performance and reliability under extreme conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
