    Jun 13, 2012 · "But but but isnt 4140 an oil hardening steel" says I. "Yes essentially but in larger sizes etc etc you will not get a quick enough quench to get the required hardness using oil". "Hence we quench in water, in fact our water has a small amount of polymer in it so it probably quenches a little bit quicker than straight water".I am going to post this I think I know what the issue was but would like some other input.
