The effects of heat treatment ( quenched at 860 〜950 °C + tempered at 200 ~ 400 ℃ ) on the microstructure and mechanical properties of a new medium carbon 40CrMnSiB low alloy ultra-high strength steel (0. 41C
0. 84Cr
0.76Mn
1.44Si
0. 006B) are investigated by OM
SEM and JMatPro7. 0 analysis techniques. The results show that with quenched at 920℃ . and tempered at 300 °C
the mechanical properties of the steel reach the best toughness matching
