Spoolarc 40 is a submerged arc wire that is typically used to weld carbon and low alloy steels. It contains 1/2% Mo and elevated levels of Mn which make it suitable for stress relieved applications requiring 80 ksi tensile strength.
Designed for single or multipass wire for welding carbon and low alloy steels. Produces good as welded and stress relieved impact toughness. Weld metal tensile strength is in excess of 80 ksi (552 MPa). Applications include pressure vessel fabrication and other similar welds which require postweld heat treatment.
