SPOOLARC 44

Spoolarc 44 is a high Mn, 1/2% Mo wire with a 0.6% Ni addition designed for single or multipass welding where high strength and impact toughness are required. It maintains 80 ksi after long-term, 50 hours or more, stress relieving.

Features

Designed for single or multipass welding where high strength and impact toughness is required. Weld metal tensile strengths of 80 ksi (552 MPa) are maintainable after long term stress relieving (50 hrs or more). The presence of Ni in the wire chemistry helps increase low temperature impact toughness. Applications include pressure vessels, structural supports, and some heat treatable valves and fittings.
