With this research, steel abrasion experiments had been performed on an automatic grinding gadget for stainless steel 304. Experiments had been performed at various grinding occasions for instances of heat-treated samples and samples of their source condition. The martensite stage transformation for the duration of grinding was researched via microstructure observation outcomes and surface hardness, microhardness measurements. The investigate final results exhibit which the abrasion resistance of SUS304 metal increases noticeably in the event the sample is quenched in h2o While the floor hardness isn't going to enhance. This phenomenon might be described by the appearance of the martensite section by way of a stage transformation mechanism due to plastic deformation of the fabric's surface area layer.
Observation outcomes show that after grinding, an important number of martensite period appears over the floor of heat-addressed samples. The macro surface area hardness from the metal isn't going to improve, but microhardness in various places shows a transparent big difference, specifically in areas with high concentrations of martensite.
Key terms: Stage transformation, warmth therapy, abrasion resistance, chrome steel 304, abrasion experiments.
