For a wear resistant part,we do not need to consider hardfacing if the casting could fully meet the requirements from the aspects of cost, working performance.Then, why should we choose hardfacing ? We introduced micro casting-hardfacing process when casting can not reach the required index such as wear resistant parts of service life and quality, that is what we said to strengthen the quality of a wear resistant part.

There are a lot of hardfacing methods, such as gas welding, manual arc welding, gas shielded arc welding, submerged arc welding, open arc welding etc. Hardfacing remanufacture is to has a qualified wear resistant materials welded on the mild steel plate, composite carbide were evenly distributed in the matrix after welding process, the formed austenitic matrix has a high tensile strength and high stress wear resistance, also has a good welding surface and moderate impact resistance, so as to improve the service life of wear parts (can work 1.5 times better than new products ).

YAOYU Wear Resistant New Materials Co.,ltd manufacturer chromium carbide overlay plate by using self-produced Germany VAUTID welding wires, the surfacing process is self shielded flux cored open arc welding.
