YDM227
Description:
YDM227 is a submerged arc flux-cored welding wire for surfacing, which has strong anti-cracking ability and does not generate cold cracks and hot cracks when surfacing. Surfacing metal wear resistance, anti-fatigue ability. Welding arc stability, easy slag, weld forming beautiful.
use:
Mainly used for hot roll and roll billet repair and composite roll manufacturing. Can also be used for other requirements of wear-resistant, high temperature oxidation, thermal fatigue resistance of the important components of the surface surfacing.
