Abstract

Abstract

In the current study, the sharpness test and microstructure characterization for the 30Cr13 cutter under the regime of quenching and tempering processes was performed to investigate the relationship between distribution and type of carbides and sharpness of cutting tools. After the tempering process (300 ℃, 30 min), the initial sharpness and cumulative thickness cuts of the cutter decrease by 34.6% and 26.4%, respectively. However, the tool under the state of tempering have a less loss of sharpness in single cutting and a better durability, and the following reasons should be considered for these results: (i) the increase of the M23C6 carbide precipitates after tempering enhances wear resistance of tools through dispersion strengthening and (ii) the reduction of carbon in the quenched martensite leads to lower hardness and sharpness of the cutter.
- low-carbon martensitic stainless steel,
