WP7V is a Dörrenberg, high performance, next generation, special alloy (Cr-Mo-V), combining superior heat resistance, high temperature corrosion resistance, toughness and strength for the most demanding applications. Is this one of Dörrenberg’s new special steels, am I describing it right? It can be water cooled, & is secondary hardenable with very high toughness, good compressive strength, and high wear resistance also at high temperatures.
WP7V is used for forming dies and die inserts with flat cavities subject to high stresses. Very suitable for cutting tools for sheets >7mm. Piercing punches and shear blades subject to high stresses as well as rollers, thread rolling tools, tools for the plastics industry.
