Multi metal base hardfacing alloy

Abstract

A multi metal base hardfacing alloy is provided. The atom percent of each element in the alloy is smaller than 35%. When the alloy is used as a welding material, it has advantages such as low operating temperature, better physical strength hardiness, acid resistance, basic resistance, anti-oxidation, and interface obturation.
