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

Corodur Fülldraht GmbH may change the characteristics of the wire without notice. Statements on composition and application are just for the applier's information. Statements on mechanical properties always refer to the all-weld-metal according to valid standards. We recommend the applier to check our products for their special application autonomously.
