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 |
