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 .
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
