Type
Highly basic flux cored wire for submerged arc welding
Applications
Earthmoving equipment, offshore, drilling platforms, lifting, vessel building, transport, etc.
Properties
Remarkable crack resistant weld metal in combination with very low hydrogen content. Therefore, suitable for the economic processing of fine grained structural steels up to 460 MPa yield strength. Excellent welding properties in combination with FL 155 high basic flux even in narrow gabs. Excellent wetting properties compare to solid wires that results in a bigger parameter range and improved deposition rate.
