COROLOY 520 W deposits a Cr- Co- Mo- Ti- Al- W- alloy in a nickel base. The weld metal is a precipitated, easily hardened alloy with an exceptional combination of high temperature mechanical properties, formability and corrosion resistance. The alloy can be used for hot forging dies, hot working steels, hot shear blades, etc. To obtain a crack-free weld, the base material should be preheated to 350°C and held. After the
welding is completed, the cooling rate should be low.
