Microstructures and properties of a novel carburizing
The hardness of 23Cr2Ni2Si1Mo steel is greater than that of 20Cr2Ni4 steel, which is coincident with the hardenability results of the two steels. In spite of the 23Cr2Ni2Si1Mo steel shows a much higher strength as compared with the 20Cr2Ni4 steel, the impact toughness is almost the same as the 20Cr2Ni4 steel, which reaches 115 J/cm 2. The
20Cr2Ni4 angle bars, 20Cr2Ni4 flanges, Pipe Fitting, Steel Pipe, Heat Exchanger and Reducer, Gasket, Tee, Pipe Fitting, Tube Plate, have all specifications. With many yeas production experience, strict control 20Cr2Ni4 chemical composition and 20Cr2Ni4 mechanical properties.
