COROLOY CO

CLASSIFICATION

DIN EN 14700 DIN 8555
T Ni2 MF 23-250-CKNPTZ

GENERAL CHARACTERISTICS

COROLOY Co is a high alloyed Cr- Mo- Co- W- flux cored Nickel based wire. This alloy is suitable for steel that encounters aggressive corrosive media as well as those steels that operate at high temperatures. This hardfacing alloy is extraordinarily resistant on impact, pressure loads and high temperature environments, which results in hardening of the deposit up to a hardness of about 420 HB with little deformation. When build-up layers are required, CORODUR 200 K is recommended as a buffer layer. It is also recommended that the base material should be preheated to about 300°C – 400°C before hardfacing. For multi layer welding low interpass temperature and low energy input is recommended.

APPLICATION

Hot forging dies, forging plant parts, hot shear blades, hammer and hammer-saddles, repair of injection moulding castings, piercing mandrels, buffering alloy for forging hammer-saddles and hammers

Datasheet

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

Datasheet

COROLOY SE 6/40

CLASSIFICATION

DIN 8555 | DIN EN 14700
MF 22-45-CGTZ | T Ni 1-45-CGTZ

GENERAL CHARACTERISTICS

Ni-, Si-, Cr-, B-alloys. These alloys give a nickel-base weld deposit. The essential characteristics correspond to the cobalt-base alloys, especially the hardness, corrosion resistance, heat resistance, wear resistance and thermal shock constancy. Applications are found in the chemical industry, nuclear technology field, etc.
