Product Description
Features and Scope:
Penetration of low carbon high manganese steel, 15Mn steel with similar performance. Mn (W mn 0.70% -1.00%) higher carburizing low carbon steel, because it is the strength of high manganese. Ductility. Machinability, and hardenability slightly higher than 15 steel, carburizing and quenching surface soft spot less, should be cementite. carbonitriding treatment, the surface wear and heart by the Department of toughness, good overall performance. After hot rolling or normalizing good toughness. For gears. Crank shaft, bracket. More chain. Screws. Nuts. Welding structural parts, sheet metal suitable for making oil tank. Tools in cold areas, such as cream cans. [1]
