An excellent choice for a highly Mn-Cr- alloyed flux cored wire is the CORODUR® 250 K. 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 non-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.
