UNS R31233(ULTIMET)

Introduction:

ULTIMET is a cobalt-based alloy with exceptional resistance to galling, cavitation erosion, slurry erosion, liquid droplet impact. Ideal welding material with exceptional ductility and resistance to weld cracking, very easy to apply as an overlay, multiple layers appliable with little to no preheat.
