COROLIT® E 21

CLASSIFICATION

DIN EN 14700
E Co1

GENERAL CHARACTERISTICS

AC-weldable hardfacing electrode with an alloyed core and a recovery of 160 %. The deposit is a cobalt base alloy of high tenacity as well as extreme corrosion and heat resistance. The weld metal is highly resistant to impact and is work-hardening up to 45 HRC.
Working temperature should be kept between 400° and 600°C, depending on base material and type of construction. Slow cooling, if necessary oven cooling, is recommended for low alloyed and austenitic steels. Subsequent heat treatment (stress relief at 700°C approx.) is not necessary, except on large structures.

APPLICATION

Hardfacing of cutting edges of long knifes and other tools used in the wood, plastic, paper, carpet and chemical industry.

COROLOY® E 520

CLASSIFICATION

DIN EN 14700
E Ni2

GENERAL CHARACTERISTICS

COROLOY E 520 is a lime basic coated high Cr- Co- Mo- Ti- Al- W- alloyed nickel based electrode. The deposit is a precipitation hardenable alloy with an exceptional combination of high temperature mechanical property capabilities, forge ability and corrosion resistance. The alloy can be used for a great number of critical high temperature applications.

APPLICATION

Hot forging hammers, repairs, NiMoNic alloys.

COROLOY® E Co

CLASSIFICATION

DIN EN 14700
E Ni2

GENERAL CHARACTERISTICS

High alloyed nickel based AC electrode with 160 % recovery. The COROLOY E Co type deposit has outstanding physical characteristics and is resistant to both, oxidation and reduction corrosion. It work hardens under impact and by machining to app. 400 HB even at high temperatures – without deforming the deposit. Thick layers should be buffered with CORODUR E 29/9.
COROLOY E Co is used in general for surfacing of all work-pieces subject to mechanical stress combined with corrosion and/or to high temperatures (from 400 – 750°C).

APPLICATION

Main applications: Surfacing of hot working tools as hot shear blades, punches, deburring tools, swages, dies, press tools, milling rolls and valves, etc. To achieve a crack-free overlay, the base material should be preheated to 300 – 400°C, depending on the alloy.

Datasheet

CORODUR® E NIFE 31

CLASSIFICATION

DIN 8573 | AWS A 5.15
E NiFe-1 - BG 11 | E NiFe-CI

GENERAL CHARACTERISTICS

Basic-graphite special coated electrode with a bimetallic ferro-nickel core wire which allows very fast fusion on direct current as well as on alternate current without any risk of overheating. Suitable for joining all types of grey cast iron and also for joining cast iron with steel, but especially for nodular cast iron. The colour of the deposit is very similar to the base material, and corrosion
will be identical to the base material later on. This electrode excels by very high crack-resistance and high tensile strength of the weld metal. Even in refined zones the seam is still machinable.

APPLICATION

GG 10, GG 40, GTS 35, GTS 70, GTW 35, GTW 70, GGG 40, GGG 80
