Dhruv Metals, a well-respected manufacturer and supplier located in Hyderabad, India, specializes in crafting high-performance Super Duplex Steel Hex Bars that are designed to meet the toughest industrial standards. These hex bars are produced in line with ASTM A276 and A479 specifications, making them renowned for their exceptional corrosion resistance, impressive tensile strength, and excellent weldability. Thanks to a balanced microstructure of austenite and ferrite, they deliver outstanding mechanical performance even in the most challenging environments. Dhruv Metals serves a diverse range of industries, including offshore, marine, chemical, oil & gas, and desalination plants, providing precision-machined products that consistently meet quality standards and are delivered on time around the globe.
The Super Duplex Steel Hex Bars from Dhruv Metals are composed of roughly 25% Chromium, 7% Nickel, 3.5% Molybdenum, along with trace amounts of Nitrogen and Manganese. This unique blend offers remarkable resistance to pitting, crevice, and stress corrosion. The dual-phase microstructure contributes to impressive mechanical properties, boasting a tensile strength of at least 800 MPa, yield strength of at least 550 MPa, and an elongation of 25%–30%. With a density of 7.8 g/cm³, these bars also demonstrate excellent fatigue resistance and superior toughness, making them perfect for demanding load-bearing and corrosive industrial applications.
