Material Notes:
A premium grade H13 hot work tool steel featuring:Very good toughness properties meeting the requirements of NADCA 207-97, and the superior quality levels of NADCA 207-2003Very good heat checking resistanceGood temper resistance and high temperature strengthExcellent polishability and texturabilityManufactured for flats greater than 18” in thicknessThe term SUPERIOR refers to Bohler’s unique processing method which includes electro-slag remelting (ESR) to obtain a steel with superior mechanical properties. Applications: Dies, cores and inserts for the high pressure die casting of aluminum, magnesium and zinc alloys. Hot forging, shearing, pressing and extrusion tooling including: dies, die holders, liners and stems. The excellent polishability and toughness properties of W302 Superior also make it an excellent choice for demanding larger block plastic molding applications.
