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

Question for the metal guys.....Heating and bending a sway

18/02/2012· 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.

Tempering (metallurgy) Wikipedia

Tempering is a heat treatment technique applied to ferrous alloys, such as steel or cast iron, to achieve greater toughness by decreasing the hardness of the alloy. The reduction in hardness is usually accompanied by an increase in ductility, thereby decreasing the brittleness of the metal. Tempering is usually performed after quenching, which is rapid cooling of the metal to put it
