How to choose the material of the chain

The selection of performance is not less than 45 steel material manufacturing is ideal, scraper chain to overcome a lot of friction resistance, bear a lot of roller chain dynamic load and static load, so the scraper chain in manufacturing and welding after heat treatment, so that its chain has a high strength, toughness and wear resistance. Usually the chain plate in the material selection of 45Mn2 tempering treatment, hardness HRC62, recently also used 20CrMnTi and other high alloy steel materials, which has good mechanical properties, longer service life. The pin is made of 45 steel or 40Cr tempering treatment, and its quenching hardness is HRC38-43.
