An overlayer for a use on industrial components such as steel mill caster rolls which require enhanced abrasion, corrosion, and gall resistance. The overlayer has relatively lower carbon levels and relatively higher molybdenum levels relative to other alloys used as overlayers, The overlayer has reduced susceptibility to sensitization and enhanced corrosion resistance.

Abrasion, corrosion, and gall resistant overlay alloys

A method for depositing corrosion and wear resistant high alloy overlayers on industrial component substrates. Dilution of alloying components from out of the overlayer into the substrate is minimized by use of electroslag surfacing onto horizontally positioned surfaces of the substrate using oscillating wire.

Electroslag surfacing using wire electrodes

A low alloy steel for use in building up industrial components subjected to service conditions requiring good impact toughness, resistance to tempering, and resistance to temper embrittlement, for example, for use as a build up layer for steel mill caster rolls and a submerged arc welding wire for deposition thereof. The composition of low alloy steel has less than about 0.1% C by weight, between about 1.5% and about 5.0% Ni by weight, and between about 0.5% and about 3.0% Mo by weight. Vanadium, Cr, and other carbide-formers are excluded from the low alloy steel sufficiently to avoid any significant precipitation of carbides upon deposition of the low alloy steel by welding onto an industrial component.
