GM 70S2, ER 70S2

CLASSIFICATION
AWS A-5.18: ER 70S-2

DESCRIPTION
Copper coated filler wire has Al, Ti and Zr as strong deoxidants with Mn and Si content. The wire has very low impurities such as S, P etc and is suitable for applications involving subzero temperatures up to -30°C. This has advantages of semi–killed steels or rusty and contaminated joint area. Smooth flow and gives shiny bead under optimum welding conditions. The deposited weld meet x-ray / radiographic quality code requirement.
