Duplex Steel Bars and Forgings are high-performance stainless steel products known for their excellent combination of high mechanical strength and superior corrosion resistance. These materials offer outstanding resistance to stress corrosion cracking, pitting, and crevice corrosion in harsh industrial environments.
Duplex Steel Bars & Forgings are produced through controlled hot rolling and forging processes to ensure uniform microstructure, high toughness, and long service life in high-pressure and load-bearing applications.
Duplex Steel Bars and Forgings are available in standard duplex grades suitable for a wide range of industrial applications. The most commonly supplied grades include Duplex S31803 (UNS S31803) and Duplex S32205 (UNS S32205), offering excellent corrosion resistance, high yield strength, and excellent weldability.
