Quenched and Tempered Steel Plate is the combination two processes that make it harder, tough and more weldable and ductile than ordinary carbon steel plate, as they are less brittle and more ductile without sacrificing too much hardness. The process involves heating the plate and then rapidly cooling it to set the components into place as quickly as possible. the combination two processes that make it harder, tough and more weldable and ductile than ordinary carbon steel plate.
The amount of time it is tempered is the determining factor to how much hardness is removed. A514 Steel Plate is
