Description

Duplex Stainless Steel Rod

Duplex Stainless Steel Rod is a high-performance solid bar made from duplex-grade stainless steel, which has a balanced microstructure of austenite and ferrite. This unique composition provides exceptional strength, stress corrosion resistance, and superior mechanical properties compared to standard austenitic grades like SS 304 or 316. Duplex rods are ideal for high-stress, corrosive environments, particularly in industries such as oil & gas, marine, chemical processing, and desalination.

As leading Duplex Stainless Steel Rod manufacturers in India, we utilize cutting-edge technology and precision engineering to deliver rods with superior toughness and stress corrosion resistance. We support metal fabrication services and custom lengths as per project needs.
