Quenching Test on 8Cr4MoV Alloyed Forged Super-Deep Hardening Layer Cold Work Roll Steel

摘要：

Alloyed forged super-deep hardening layer cold work roll steels were tested in laboratory containing about 4％Cr, 0.8％C, and appending a little of N and Re in it individually or together. The steels were smelt in 50 kg vacuum induction furnace primarily, then forged, quenched and tempered in turn, simulating the making process of the cold work roll. The steels mechanics performances, microstructures and hardenability by end quenching test were compared each other, the better was put into quenching test, then through analyzing the microstructure and microhardness of quenching specimen, the optimum quenching temperature of it had been got, and this was very helpful for making super-deep hardening layer cold work roll.
