AUTOTHERME GRADE-V

AWS: SFA 5.23 EB8 EN ISO CODE: 24598-B SU9C1M

Autotherme Gr-V (9%Cr-1%Mo) is a copper coated solid wire for the submerged arc welding of medium and high strength structural steels. These wires are suitable for welding of creep resistance and similar composition high strength steels. The weld metal possesses good high temperature properties. It deposits sound weld with excellent mechanical properties especially suitable for welding of pipes and tubes of matching compositions in power plants, Refineries, Petrochemicals, Fertilizer, etc. Suitable for welding of ASTM steels: A182-F9, A336-F9, A199-T9, A200-T9, A213-T9, A335-P9, A369-FP9, A217-C12, A387-Gr9.
