Air cool after heat bending is technically best in this case so the steel molecules are not put under the extra stress from quickly quenching the steel. If you are in a hurry let it air cool for a minute then quench it. If you cannot get it to a full of medium red then you can simply bend it cold.
The heat is to be localized and it simply allows the molecules to move about more readily.
