Designed a medium manganese cast steel used to making hammer, which has good work-hardness under non severe impact condition.
设计了一种中锰铸钢锤头材质，其在非强冲击条件下具有较好的加工硬化效果。

The hardness obtained from a given treatment depends on the quenching rate, the carbon content, and the work size.
通过给定的热处理所得到的硬度取决于淬火速率、含碳量和工件尺寸。
3
The creep strain rate sensitivity can be determined from the relationship between the creep hardness and creep strain rate by the definition of "work of indentation".
