SKD 11 steel is a tool steel which is often applied in the manufacturing industry, such as cutting, punching, stamping tools, shear blades, dies and others. And in it’s application, of course steel must have a hard structure, strong and touhgness affected due to external forces causing deformation or change in shape. To improve the quality, heat treatment is required on the steel by providing austenizing, quenching and tempering temperature variations 400 °C, 550 °C and 650 °C. Which purpose to determine the hardness and microstructure of the tempering variation results. The first step of cutting material SKD 11 steel, followed by austenizing process up to 1050 °C and then quenching process (fast cooling) with medium water and continue the process of tempering variation 400 °C, 550 °C and 650 °C. After the heat treatment was complete, take hardness test and view the microstructure of the SKD 11 steel. At temperatures tempering 400 °C showed the highest hardness value of 56.5 HRC, followed by tempering temperatures 550 °C at 52.9 HRC and the lowest occurred at temperature tempering 650 °C at 39.1 HRC. Microstructure formed pearlite and martensite. Then the higher temperature tempering then the declining value of steel hardness SKD 11.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
