COROLOY 520 W
CLASSIFICATION
DIN EN 14700 DIN 8555
T Ni2 MF 23-40-CKPTZ
GENERAL CHARACTERISTICS
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.
APPLICATION
Hot forging hammers, hot forgimg dies, pilger mandrels, highly heat resistant impact loaded
claddings, repair von NiMoNi alloys
