THE WEAR RESISTANT ALLOY FOR BUILT-UP WELDING

摘要

PURPOSE: The present invention relates to an anti-abrasive alloy for overlay welding suitable for application to structural member of dust collector and raw material storage facilities where abrasive particles severely collide with structural member. To solve such a problem, both W and B is simultaneously added in Fe-Cr based hard facing alloy. CONSTITUTION: The anti-abrasive alloy for overlay welding is characterized by comprising C 1.5-3.5wt.%, B 0.5-2.0wt.%, Si 2.0wt.% or less, Mn 2.5wt.% or less, Cr 8-25wt.%, W 5-20wt.%, a specific amount of Co, and a balance of Fe.
