Analyzing the difference between hardenability and hardenability of T10 steel and 20CrMnTi steel from the perspective of alloying principle
Hardenability is the maximum hardness that can be obtained when steel is quenched. Generally, it mainly depends on the supersaturated carbon content of martensite. The larger the supersaturated carbon content, the higher the hardness after quenching. Hardenability is the ability to obtain martensite. It mainly depends on the amount of alloying elements. Generally speaking, the more alloying elements and types, the better the hardenability.
Because the carbon content of T10 steel is about 1% and that of 20CrMnTi steel is about 0.2%, excluding the influence of specific heat treatment process, it is obvious that T10 steel has higher hardenability.
In addition, because T10 steel does not contain alloy elements, 20CrMnTi steel contains elements Cr and Mn which can improve the hardenability very well. Excluding the influence of specific heat treatment process, it is obvious that 20CrMnTi steel has higher hardenability.
