20NiCrMo2H Gear Steel Bar
Equivalent to ASTM SAE8620H , 20NiCrMo2H steel is from the United States AISI (SAE) standard "H" structural steel imported steel, equivalent to the Chinese standard 20CrNiMoH (GB / T5216-2004). Cr-Ni-Mo-based case-hardened steels that are widely used in carburizing and carbonitriding in the United States have low Cr, Ni and Mo contents, good malleability, machinability, and weldability.
Parts can be Direct quenching from the carburizing temperature, carburizing process in the formation of smaller tendency. Mainly used in the manufacture of all kinds of heavy vehicles, heavy excavators, heavy cranes, heavy machine tools and other heavy machinery transmission gears, gear shafts, and off-road jeeps, motocross and other small-sized need to drive large torque transmission gear shaft and its processing Small deformation, hardenability with narrow and stable, is one of the most stringent quality requirements gear steel varieties.
