Low-carbon mild steel won't get very hard, or very brittle, now matter how
quickly it is quenched. The three main factors to consider when heat-treating
ferrous alloys are 1) alloy composition - how much carbon and which and what
percentage of other alloying materials are present, 2) temperature and 3) speed
of cooling or quench. Oil quenching cools the material more slowly than water,
but faster than air, water is faster, brine is fastest. I agree with Fred that
you should do a little research before you go foolin' around with this process,
and stay away from safety-critical items.
