Abstract

Supercarburizing, also referred to as high-concentration carburizing, carbide-precipitation carburizing, and carbide dispersion, is a carburizing method that results in a large amount of dispersed particulate carbide, with carbon content as high as 2 to 3%, to obtain surfaces with high hardness and good wear resistance. This article briefly reviews the process of supercarburizing using conventional carburizing steel as well as steels developed for supercarburizing, including 20CrMnMo steel, 20Cr2Ni4 steel, 35Cr3SiMnMoV steel, and 20CrMnTi steel. In addition, it discusses supercarburized steel composition, carburizing characteristics, mechanical properties testing, and microstructure analysis of 35Cr3SiMnMoV steel.
