High-aluminum boron-containing die steel with resistance to zinc-induced hot corrosion for severe plastic deformation of zinc alloys at elevated temperature and preparation method thereof

Abstract

A method of preparing a high-aluminum boron-containing die steel for severe plastic deformation of zinc alloys at elevated temperature, in which a cast ingot is obtained by sand casting, and then subjected to homogenization, austenitization, hot-die forging and cooling to obtain a heat-treated piece. The heat-treated piece is quenched and tempered to obtain a forged piece, which is subjected to finish machining to obtain the high-aluminum boron-containing die steel. A high-aluminum boron-containing die steel prepared by such method is further provided.
