Corodur Nicrmo 22 description: CORODUR NiCrMo 22 is a flux cored wire which is suitable for medium alloyed steels and high strength steels. This alloy can also be used as a buffer and build-up layer (multiple pass). When NiCrMo 22 is used as buffer and build-up layer for rolls and parts followed by a hard surfacing alloys, the preheat and interpass temperature should be chosen depending of the C-contents of the base material). The weld deposit is highly crack resistant and is highly resistant to impact and pressure wear.
