FIller Metal Breakdown

Supercored 70SB

Supercored 70SB is a basic flux cored wire with excellent characteristics and is suitable for steel with a tensile strength up to 600MPa. It`s flux cored wire which deposits very low hydrogen weld metal, So deposited metal shows superior crack resistance, excellent toughness at low temperature at -20℃~-30℃(-4~-22℉)
