What is Duplex & Super Duplex Steel Coated Electrodes?
Duplex and Super Duplex Steel Coated Electrodes feature a balanced composition of chromium (21–26%), nickel (4.5–7%), molybdenum (2.5–4%), nitrogen (0.15–0.3%), and trace elements for enhanced corrosion resistance and strength. These electrodes provide excellent weldability and resistance to pitting, stress corrosion, and crevice attack. Mechanical properties include high tensile strength (700–850 MPa), yield strength (450–550 MPa), and elongation of 25–30%. The weld metal offers a fine austenite-ferrite microstructure, ensuring superior toughness, durability, and performance in aggressive industrial and marine environments.
