Low-carbon carburized steel with high manganese content (WMn 0.70%. 1.00%) has slightly higher strength, plasticity, machinability and hardenability than 1015 steel due to its high manganese content. There are less soft spots formed on the surface during carburizing and quenching, so carburizing and carbonitriding treatment should be carried out to obtain comprehensive properties with wear-resistant surface and good toughness at the core. Good toughness after hot rolling or normalizing. Apply to gears and crankshafts. Supports, hinges, screws, nuts, riveted structural parts. |
