Microstructure and Mechanical Property of 4Cr3Mo2VNiNbB Hot Working Die Steel

Abstract

Abstract

The mechanical properties and microstructure of hot work die steel 4Cr3Mo2VNiNbB were studied. The results show that the EAF+LF+VD+ESR process can produce high-purity steel 4Cr3Mo2VNiNbB; after quenching and tempering heat treatment,with transverse impact and excellent tensile properties, and homogeneous microstructure; mechanical properties and microstructure of the oil cooling condition are not very different from those of air cooling.
