The material of the gear shaft is carbon steel and alloy steel.
Such as 40, 45, 50, 40Cr, 50Cr, 42CrMoA, etc., the commonly used
heat treatment method is tempering, and quenching treatment in
important parts. When the requirements are higher, high-quality
low-carbon alloys such as 20CrMnTi, 20CrMo, 20MnCr5, 17CrNi5, and
16CrNi can be used for carburizing and quenching treatment to
obtain higher surface hardness and higher core toughness, spline
shafts.
