I know this has been kicked around before but couldn't find the thread. Help me out here, is there an advantage to tempering in the 400-450 deg F range as apposed to the 900 deg F range. Seems to me there was better corrosion resistance or something. The lower temp is a lot more user friendly as well. I have done the heat treat and cryo and now want to temper back to the 59-60 Rc range.
Thanks, Mike
 
Mike: About 90% of my customers ask me to do the 950 temper, the others ask for the 400 temper.Hope this helps you. Paul.
 
Thanks Paul and Jerry,
Can you tell me what the outcome is for the two different temps. Do they test to +/- 60Rc at both temps? Is the temper time the same ie: 2 x 1 hour. They seem like such drastic differences in temp that there should be a different outcome.
Thanks, Mike
 
Mike: Your 14-4 steels have a secondary tempering range like D-2 and other tool steels at 400 Deg. F you get a 60 R/C, then at 950 Deg. F it comes back up to 60 R/c. All tempering should be 2 tempers at 2 hrs. per temp. Paul.
