SAW Wire
AUTOTHERME GRADE-S
AWS: SFA 5.23 ENi3
EN ISO CODE:
Copper coated with 3.5% Ni solid wire for submerged arc welding. These wires are suitable for similar composition high strength & quenched steels.
Autotherme Grade-S low alloy solid wire is suitable for welding of similar grade
steels. The weld metal possesses high tensile strength, Excellent CVN toughness at
-70 C 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 A203Gr.E, ASTM A203Gr.D, ASTM A352 LC3 & ASTM A352 LC4 etc.
