... at temperatures ranging between 425 °C and 540 °C. In these conditions, the decomposition of cementite yields graphite, which reduces tensile strength. This effect is a faster strength reduction due to the globulization of carbides. Therefore, steels must include alloying elements with strong carbide-forming...
