1.Good wear resistance;
2.Careful selection of material, good machining quality;
3.Strict heat treatment process control;
4.Honesty for each client

Applicable scope:

Any sprocket with higher strength and good cutting ability, medium cold-drawn deformation, poor welding ability, weldable after quenching or tempering, no temper brittleness during heat treatment, low hardenability. It can be used as a small-section hardened&tempered part with higher bearing load or large normalized part with low stress or surface quenched part with wear-resistant surface but without no strength requirements for core.

Materials and heat treatment of sprocket:

Material	Heat treatment	Tooth surface hardness	Applicable scope
15, 20	Carburizing, quenching, tempering	50 to 60HRC	z≤25 sprocket with impact load
35	Normalizing	160 to 200HBS	z>25 sprocket under normal working conditions
45, 50 ZG310-570	quenching, tempering	40 to 50HRC	z≤40 sprocket without fierce impact load and operated under the wearing conditions
15Cr, 20Cr	Carburizing, quenching, tempering	55 to 60HRC	Z<25 sprocket with dynamic load and high transmission power
40Cr, 35SiMn 35CrMo	Quenching, tempering	40 to 50HRC	Sprocket with higher strength and wear-resistant teeth
Q235, A5	Annealing after welding	about 140HBS	Sprocket at medium speed and transmission power
Not below HT150	Quenching, tempering	260 to 280HBS	z>50 driven sprocket with complex shape and poor precision
