Mechanical properties and thermal stability of a maraging steel with borides, deposited with a flux-cored wire

Abstract

The results of investigations of the mechanical properties and thermal stability of Fe–Ni–Mo–Cr–B–Si–Ti–Al maraging tool steel, containing boron compounds and produced by surfacing, are presented. The effect of borides on the nature of hardening of the composite material is described. The role of borides in the increase in the thermal stability of the steel designed for deposition of metal cutting tools is analysed.
