Default Re: Heat Bluing

Bill, The time require to straw or heat blue PO8 small parts will vary widely with the mass (weight) of the part in question, So I check them every 10 minutes and pull out the ones that look done. I normally put them in the oven @450 and they must be VERY CLEAN or the finish will be splotchy.
