In this research, steel abrasion experiments have been executed on an computerized grinding device for stainless steel 304. Experiments had been carried out at diverse grinding periods for cases of warmth-addressed samples and samples of their source point out. The martensite section transformation throughout grinding was studied by way of microstructure observation benefits and floor hardness, microhardness measurements. The investigation effects exhibit the abrasion resistance of SUS304 steel improves considerably when the sample is quenched in water Although the surface hardness does not increase. This phenomenon can be stated by the looks on the martensite stage through a section transformation mechanism on account of plastic deformation of the material's surface layer.
Observation success exhibit that just after grinding, an important number of martensite stage seems to the surface area of warmth-dealt with samples. The macro surface area hardness from the metal will not improve, but microhardness in various places shows a transparent big difference, especially in areas with large concentrations of martensite.
Keywords and phrases: Section transformation, heat treatment, abrasion resistance, stainless-steel 304, abrasion experiments.
