摘　　要：本文对经真空淬火、回火和盐浴炉加热等温淬火、回火并达到四种不同硬度要求的 30CrMnSiA钢的力学性能进行了系统的试验研究。结果表明 ,除个别情况外 。Mechanical properties of 30CrMnSiA sfeel which is vacuume hardened and fempered as well as salt bath heating-austempered and tempered and four different hardness requirements of which are fulfilled have been sgstematically investigated in this paper.The test results show that traditional salt heating-austempering may be replaced by advanced vacuume hardening with the exception of individual circumstances.
