Bohler-Uddeholm BÖHLER W302 SUPERIOR® Premium H13 Tool Steel
Categories: Metal; Ferrous Metal; Tool Steel; Hot Work Steel

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 207-2003
  • Very good heat checking resistance
  • Good temper resistance and high temperature strength
  • Excellent polishability and texturability
  • Manufactured for flats greater than 18” in thickness
The 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.

Key Words: AISI H13; DIN 1.2344; JIS SKD61; ISO 40CrMoV5
