Forging of DIN 100Cr6 Bearing Steel
DIN 100Cr6 alloy steel is forged at 927 to 1205°C, and should not be forged below 925ºC. A post-forge equalization treatment is recommended at 745ºC for 4-6 hours followed by air cooling for SAE/AISI 52100 steel.
Heat Treatment for DIN 100Cr6 Bearing Steel
DIN 100Cr6 alloy bearing steel is heated at 816°C followed by quenching in oil. Before performing this process, it is subjected to normalizing heat treatment at 872°C followed by slowly cooling in order to reduce the machining stress.
