Effect of heat treatment process on impact properties of GBT 11251 30CrMnSi steel steel plate. In order to study the hardness and impact properties of GBT 11251 30CrMnSi steel with different quenching processes, two heat treatment processes were selected to study. First process is the conventional quenching process, the quenching temperature is 910 , tempering temperature according to 230,
GB/T 11251 30CrMnSiA alloy steel plates - BEBON steelGB/T 11251 30CrMnSiA alloy steel plates are medium carbon tempered steel with high strength and poor welding performance. After quenching and tempering, 30CrMnSiA alloy steel plates have high strength and toughness and good hardenability. GB/T 11251 30CrMnSiA alloy steel plates
The hardenability of the steel is good. GB/T 11251 40Cr hot rolled structure steel plate is also suitable for cyanidation and high frequency quenching in addition to quenching and tempering treatment. The cutting performance is better when the hardness is from HB174 to 229, the relative machinability is 60%.
