Steel Hardening by Quenching
The Hardening Power Apparently Lags. In the cooling- curves of the five series of steel which we have just discussed, running from the softest basic steel to very high-carbon tool-steel, we note that each has a marked retardation which reaches a maximum in the neighborhood of 660° C. (1220° F.).
Steel - Treating of steel | Britannica.com
The heads of rails are sometimes heat-treated in-line by induction heating coils, air quenching, and tempering by a controlled use of the heat retained in the rail after quenching. Heavy-walled structural shapes are sometimes water-quenched directly after the last pass at the rolling mill and also tempered by the heat retained in the steel.

Hadeed - Wikipedia
In 1988, Hadeed introduced a new technology (Bar Quenching) to its rolling mills in Jubail for the manufacture of concrete reinforcing bars. This process involves high pressure surface quenching followed by self-tempering. As the bar emerges from the last rolling stand, the surface temperature is rapidly reduced by high pressure water jets.
BAR QUENCH FIXTURE - VAN DORN CO,US

Question for the metal guys.....Heating and bending a sway ...
Feb 18, 2012· Has anyone done this successfully, and had it on a car for some time to see if there is any failure? My thought is if you heat it up and bend it to the desired location, then reheat the material above its critical temperature (I am assuming 4130 or 4340 steel was used) and then quench the material, I should have its stiffness close to where I started with.
