Özet
The present study investigates the impact of cooling media on microstructure, wear and mechanical behaviour of as cast X210Cr12 tool steel which is frequently employed in cutting and shaping tools. Furnace, still oil and agitated oil bath cooling of X210Cr12 tool steels were employed to observe the effects on microstructural and structural characterization, wear behaviour, hardness and mechanical strength. Structural analysis revealed the presence of Cr3C2 and Cr7C3 carbide precipitates, alpha ferrite and austenite in varying amounts with respect to quenching conditions. The highest hardness value of 860 HV and the lowest coefficient of friction were obtained from quenching in agitated oil bath. The lowest tensile strength values were obtained by still oil bath, and a higher percentage of elongation occurred with agitated oil bath. It was concluded that quenching parameters are important in optimising the properties of X210Cr12 tool steel, offering potential for enhancements in microstructure and mechanical properties.
