What is W302 tool steel?
Austrian (Böhler) W302 (also known as H13 hot work tool steel) is a hot work tool steel containing approximately 5% chromium, specifically designed for applications that are subject to thermal shock, friction, and high stress in high-temperature environments. If one wants to further enhance the purity and uniformity of the structure, electroslag remelting (ESR) can be adopted.
