What Materials Do Sprockets Have At Present

Application range of hardness after heat treatment of materials 15, 20 carburizing, quenching, tempering 50~60HRC z≤25, main with impact load, driven sprocket 35 normalizing 160~200HBS under normal working conditions, Quenching, tempering 40~50HRC 15Cr, 20Cr carburizing, quenching, tempering 50~60HRC important sprockets (Z <25) with dynamic load and transfer of high power (Z <25) 35SiMn, 40Cr, 35CrMo quenching, tempering 40~50HRC use high quality chain, Important sprocket wheel Q235, Q275 anneal 140HRB after welding medium speed, transfer medium power large sprocket wheel ordinary gray cast iron (no less than HT150) quenching, tempering 260~280HBS Z2>50 driven sprocket wheel with cloth baked-power less than 6kw, high speed, require smooth transmission and small noise sprocket wheel
