Alloy 4340 plate is another general purpose grade of steel used for industrial and machining applications. The inclusion of Nickel in Alloy 4340 helps simplify heat treatment. In addition, the Nickel in Alloy 4340 increases hardenability of the steel. An additional grade of Alloy 4340 is Alloy E-4340.
