With this analyze, metal abrasion experiments were being conducted on an automatic grinding gadget for stainless steel 304. Experiments had been carried out at distinct grinding instances for situations of heat-handled samples and samples within their supply state. The martensite section transformation throughout grinding was studied through microstructure observation results and surface area hardness, microhardness measurements. The analysis final results display that the abrasion resistance of SUS304 metal enhances substantially once the sample is quenched in water Regardless that the area hardness won't raise. This phenomenon might be discussed by the appearance of the martensite section by way of a phase transformation system as a consequence of plastic deformation of the fabric's surface layer.
Observation results exhibit that soon after grinding, a major quantity of martensite section appears on the floor of heat-addressed samples. The macro floor hardness from the metal will not increase, but microhardness in several places reveals a clear difference, particularly in regions with significant concentrations of martensite.
Keywords and phrases: Section transformation, heat procedure, abrasion resistance, stainless-steel 304, abrasion experiments.
