Product description
Open-arc flux cored wire for hardfacing of parts, subjected to metal-to-metal wear (adhesion), moderate impact, high thermal fatigue and corrosion at high temperatures. Especially designed for hardfacing and renovation of continuous casting rollers. Ferritic-martensitic weld metal contains Cr, Ni, Mo, V, Nb alloys and N-compounds, which increases wear resistance against cavitation and erosion. Has a very silent arc and provides smooth and easily machinable surface with no spatter. Thin slag is formed on the bead. Provides smooth and machinable surface. Typical Applications: Hardfacing of continuous casting rollers, similar rollers operating at high service temperatures and turbine blades.
