The number of teeth of the gear shaft is 85 and the weight is 1.2kg, 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 contains alloying elements Cr and Mo, in which chromium can increase the hardenability of steel and have secondary hardening effect.
Prevents the temper brittleness, remanence and coercivity, and add in some medium, resistance to corrosion in the quenched and tempered steel, molybdenum can make large cross-section parts quenching depth, hardening, improve the drawability resistance or tempering stability of steel, can make the parts under high temperature tempering, thereby more effectively eliminate residual stresses (or lower), improve the plasticity.
So 42CrMo is often used as the material of gear shaft of rolling mill in production. Its comprehensive mechanical properties are excellent and meet the quality requirements.
