HEAT TREATED PARTS
Can you suggest a good way of removing oil from parts that have been heat treated followed by quenching?
Q. Can you suggest a good way of removing oil from parts that have been heat treated followed by quenching? None of the cleaning methods, including electrocleaning and pickling, have successfully solved this problem. T.M.
A. The best way to solve this problem is to remove the oil prior to the heat treatment step. Oils of any kind that have been baked onto the surface are almost impossible to remove using conventional chemical cleaning methods. I would suggest most strongly that you contact the manufacturer of these parts and determine whether a cleaning step prior to heat treatment can be added to their process. If this is not possible you may have to consider abrasive blasting of some type to clean the surface prior to the plating process.
