High Chrome cast iron containing 12.30% chrome and 2.4-3.6% carbon can be highly alloyed and heat treated to obtain martensite or austenite or mixed matrix and special carbides of chrome. This particular carbide is a hexagonal system of Me7C3 with hardness as high as HVL200. 1600, much higher than the cementite type of carbides and common mineral […]

In the traditional production process of ductile iron, about 10% carbon scrap is generally used for the burden. This paper only deals with some problems that should be paid attention to in the process of producing nodular cast iron in an induction furnace after increasing the proportion of carbon scrap used. According to the production […]
