CORODUR® 250 K

CLASSIFICATION

DIN EN 14700 DIN 8555
T Fe9 MF 7-250-KNP

GENERAL CHARACTERISTICS:

CORODUR 250 K is a highly Mn- Cr- alloyed flux-cored wire. The fully austenitic weld material has high plasticity and acts as a plastic buffer. Deposits have a work hardening up to 500 HB, are stainless and not magnetic. CORODUR 250 K is suitable for welding buffer layers before welding over old hardfacings, because it deposits a ductile weld metal. The deposit resists high shrinkage stresses and impact loadings .

APPLICATION

Repair of: manganese steel buckets and shovels, high tensile tools , mill-shafts , clutches, crane
wheels, earthmoving undercarriage parts, gear wheels , Crusher , rails and crossovers , buffer layers

CLASSIFICATION

DIN EN 14700 | DIN 8555
T Fe9 | MF 7-200-KNP

GENERAL CHARACTERISTICS

The flux-cored wire electrode is suitable for welding parts of manganese steel ("Hadfield" type), which are exposed to high impact wear and tear. The non-magnetic austenitic deposit is tough, crack-free and work hardening. The Weld process should be adjusted as cold as possible due to grain growth and embrittlement at higher temperatures of 400°C. Typical applications can be found in the rebuilding of crusher jaws, railroad components, bucket teeth and lips, and it is designed for reclaiming worn parts of  manganese base material..

APPLICATION

Crushers, swing hammers, railway crossings, dredger buckets

CLASSIFICATION

DIN EN 14700 | DIN 8555
T Z Fe10 | MF 8-200-CKNPZ
Alloy-No. 1.4370

GENERAL CHARACTERISTICS

The austenitic weld deposit of the high-alloyed flux-cored wire electrode is corrosion resistant, work hardening, anti-magnetic and heat and thermal shock resistant up to 850°C. Depending on the high elongation (40%) the alloy is suitable for ductile buffer layers on old hardfacings, for joining dissimilar and difficult to weld steels and impact loaded parts.

APPLICATION:

Joining of Mn – Steel and difficult to weld steels, buffer layers, impact loaded parts
