8620H Material Gears And Shafts
The number of teeth of the gear shaft is 85 and the tooth height is 9.39, Forging gear shaft material selection to have good mechanical properties, often using 42CrMo steel through normalizing, tempering, induction heating quenching and low temperature tempering to achieve the required performance.
42CrMo steel belongs to ultra-high strength steel with high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and resistance to multiple impact after quenching and tempering, and good impact toughness at low temperature.
The steel is suitable for manufacturing large and medium-sized plastic moulds which require certain strength and toughness. 42CrMo is medium carbon alloy steel, the preliminary heat treatment is normalized, the main purpose is to obtain a certain hardness and optimize the internal structure, facilitate the cutting of the billet, and prepare the structure for quenching and tempering.
