Dhruv Metals, a prominent manufacturer and supplier located in Hyderabad, India, specializes in top-notch Stainless Steel 321H Bars and Rods, designed to thrive in high-temperature and pressure-heavy settings. This high-carbon variant of SS 321 is stabilized with titanium, making it resistant to intergranular corrosion while boosting its creep strength. Our 321H bars and rods are crafted in line with ASTM A276 and A479 standards, ensuring they offer outstanding thermal stability, weldability, and mechanical durability. Dhruv Metals delivers precision-finished, corrosion-resistant SS 321H bars and rods tailored to meet the demanding needs of industries like petrochemical, aerospace, thermal processing, and power generation.
Stainless Steel 321H Bars and Rods consist of 17–19% chromium, 9–12% nickel, and a carbon content ranging from 0.04–0.10%, along with titanium (at least five times the carbon content) to prevent carbide formation. This alloy boasts remarkable high-temperature strength and corrosion resistance. Typical mechanical properties include a tensile strength of around 515 MPa, yield strength of about 205 MPa, elongation of 40%, and Brinell hardness of approximately 217 HB. SS 321H retains its structural integrity and resists oxidation in continuous service up to 900°C, making it perfect for high-heat, pressure-bearing applications.
