16CrMnH is a high-performance carburized steel with high hardenability. After carburizing and quenching, it has a hard and wear-resistant surface and a tough core, with high low-temperature impact toughness, moderate weldability, and good machinability after normalizing. Widely used for carburizing parts with small cross sections and high load quenched and tempered parts with large cross sections, such as gears, shafts, spindles, worms, sleeves for speed governors, friction wheels for speed changing devices, etc. It can also replace 20CrNi steel to make parts with small cross section size, medium pressure, and no large impact load.
