Shandong Kuaima Steel Co., Ltd.
20Mn high-quality manganese structural steel plate characteristics and scope of application: high-manganese low-carbon infiltration steel, similar in performance to 15Mn steel. Low-carbon carburized steel with high manganese content (W mn 0.70%-1.00%), because of its high manganese, its strength, plasticity, machinability and hardenability are slightly higher than that of 15 steel, and the surface is formed during carburization and quenching If there are few soft spots, it is advisable to carry out carburizing and carbonitriding treatment to obtain the comprehensive performance of surface wear resistance and good core toughness. Good toughness after hot rolling or normalizing treatment. Suitable for gears, crankshafts, brackets, hinges, screws, nuts, riveting and welding structural parts, manufacturing oil tanks, etc. Farm tools in cold areas, such as butter jars.
