AUTOTHERME 70S-2 (NACE)
AWS: SFA 5.18 ER70S-2
EN ISO CODE: 14341-B G 49A 3 C1 S2
Autotherme 70S-2 (NACE) is triple deoxidized copper-coated mild steel wire for GMAW/GTAW, available in bright finish, gives smooth flow, stable arc and spatter-free under optimum welding conditions. It gives radiographic quality welds. It is designed for single and multi-pass welding of low and medium-carbon steels. Ideal for welding A36, A285 Gr. C, A333 Gr.6, A515-55, A516-70, etc.
