Technique properties:
Principal Design Features | 52100 is a high carbon, chromium containing low alloy steel that is through hardening and noted in particular for use as bearings |
Applications | Principal applications are those for bearings in rotating machinery |
Machinability | Machinability of 52100 alloy is good by conventional methods. A spherodizing anneal at 1200 F before machining will improve the overall machinability of the alloy |
Forming | 52100 may be formed by all conventional methods, including cold forging or stamping and hot or cold upset forming |
Welding | This is a high carbon alloy typically used in bearing applications where welding is not applicable or appropriate |
Heat Treatment | Heat treatment consists of heating to 1500 F followed by an oil quench for through hardening of the alloy. A normalizing heat treatment at 1600 F and slow cooling, to relieve machining stress, may be employed prior to the 1500 F and quench treatment |
Hardening | The alloy hardens from cold working or by heating and quenching - see "Heat Treatment". It also may be carburized at 1675 F and quenched after sufficient time for carburization. A second heating to 1450 F and second quench from that temperature should be used |
Forging | The alloy may be supplied as forgings and also may be subsequently forged at 2200 F down to 1700 F |
