AUTOTHERME GRADE-Q
AWS: SFA 5.23 EM4
EN ISO CODE:
Copper coated with 2.5% Ni solid wire for submerged arc welding. These wires are suitable for welding of similar composition high strength & quenched steels.
Autotherme Grade-Q low alloy solid wire is suitable for welding of similar grade steels. The weld metal possesses high tensile strength, and meets the radiographic quality requirements. Especially suitable for welding of tubes matching composition in power plants, Refineries, Petrochemicals and Fertilizer Plants. Suitable for welding of ASTM steels: Grade ASTM A514, A517, A543 type B or C etc.
