AUTOTHERME GRADE-R

AWS: SFA 5.23 EB6 EN ISO CODE: 24598-A SCrMo5

Copper coated solid wire for submerged arc welding. These wires are suitable for similar composition high strength & quenched steels.

Autotherme Grade-R 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 A213Gr.T5 A335 Gr.P5, A217 Gr.C5 etc.
