Quench Water Properties on Steel Hardening

[bovs7]

Hi all,

Is anyone able to point me in the direction of any good references relating to properties of quench water employed to harden steels? Obviously there's a few bits and pieces on temperature, but we're looking more for anything relating to water cleanliness or salt concentration (not as in a brine, but as in using regular urban water supply versus using purified or filtered water).



Thanks for any help.
