Thin Section Heat Treating
Thin Section Heat Treating
(OP)
I am interested in a standard process for the carburizing and oil quenching of a thin section steel (10B21). The part is a pinion with section sizes varying from 2.1mm to 4mm. Other than part geometry, what else can be done to avoid cracking in the quench? Thanks in advance for any information.





RE: Thin Section Heat Treating
1. Nonuniform agitation/circulation
2. Mechanical handling damage
3. Water contamination
4. Quenchant that has too fast of a cooling rate
5. Bath temperature too low
6. Oxidation of oil
7. Decarburization
8. Furnace overheating
Houghton has an excellent guide called "Houghton on Quenching" that describes the various technical aspects of quenching. I highly recommend that you contact them. For the best technical assistance, ask for D. Scott MacKenzie (Technical Specialist).
