1), the overall quenching and tempering treatment, induction quenching and tempering treatment on the surface of the tooth slot;
2), surface carburizing, quenching or tempering.
rather than steelSprocketAnd some non-standard sprockets are treated with other materials. The common materials and heat treatment process requirements of sprockets should be processed according to customer requirements.
For example, the material is No. 15 and No. 20 steel. For a sprocket with a small tooth blank and a number of teeth less than or equal to 25 with impact load, it should be carburized, quenched, and tempered, and the tooth surface hardness reaches 85.7HB15N~90.6HB15N.
For larger sprockets with medium and low speed and low power of Q235 and Q275, they should be annealed after welding, and the tooth surface hardness should reach 140HBS.
