These Duplex Steel Welding Electrodes are made from a well-balanced blend of austenitic and ferritic stainless steels, featuring key elements like chromium (21-23%), nickel (8-10%), molybdenum (2.5-3.5%), and nitrogen. This unique composition provides outstanding corrosion resistance, particularly against pitting and stress corrosion cracking. On the mechanical side, the electrodes boast high tensile strength (typically exceeding 750 MPa), impressive yield strength, and solid impact toughness, even in low temperatures. Thanks to their duplex microstructure, these electrodes are built for durability and wear resistance, making them perfect for challenging welding tasks in tough environments.
