In this study, metal abrasion experiments were conducted on an automatic grinding device for stainless steel 304. Experiments were executed at distinctive grinding times for cases of warmth-addressed samples and samples inside their offer condition. The martensite phase transformation in the course of grinding was researched via microstructure observation results and surface hardness, microhardness measurements. The investigate effects exhibit the abrasion resistance of SUS304 steel increases appreciably once the sample is quenched in water Regardless that the floor hardness will not improve. This phenomenon can be stated by the appearance from the martensite section by way of a phase transformation system on account of plastic deformation of the material's floor layer.
Observation final results show that just after grinding, a major quantity of martensite section appears over the surface area of warmth-taken care of samples. The macro area hardness on the steel isn't going to improve, but microhardness in several locations reveals a clear variance, especially in areas with higher concentrations of martensite.
