General description of products

CORODUR 250 K is a powder wire with a high Mn-Cr content. Fully austenitic welding material has high ductility and acts as a plastic buffer. The coatings are hardened up to 500 HB, are stainless and non-magnetic. CORODUR 250 K is suitable for pre-welding buffer layers over old hard deposits as it precipitates the ductile weld metal. The surfacing withstands high shrinkage stresses and shock loads.
