AUTOTHERME Mn-Mo
AWS: SFA 5.28 ER80S-G
EN ISO CODE: 14341-B G 55A Z C1 4Mo
Autotherme Mn-Mo is a copper-coated solid wire for GMAW, available in bright finish, gives smooth flow, stable arc and spatter free under optimum welding conditions. It gives radiographic quality welds. It is suitable for welding high strength fine-grained structural steels containing ~0.5%Mo. The wire is also suitable for welding of penstock pipe-line, fabrication of earth moving equipments, etc. where high tensile strength property is desired from the weld metal. Suitable for welding of ASTM steels: SA-455/ SA-455M, Gr.60, Gr.65 steels of SA-515/ SA- 515M, Gr.60, Gr.65 steels of SA-516/ SA-516M, Class 1 of A, B, C, D grades of SA- 533/ SA-533M, etc.
