BÖHLER W400 VMR
BÖHLER W400 VMR is a vacuum remelted material specially developed for tools with complex structures. The steel can be assigned to the 5% chromium steels and has a very high purity due to the special manufacturing technology. Because of its high degree of purity, the excellent homogeneity and the special alloying concept, BÖHLER W400 VMR is one of the hot work tool steels with the highest reachable toughness values. Therefore, this material is a problem solver in many areas when standard grades are no longer sufficient. In addition, Böhler W400 VMR has outstanding polishability. For this reason, the steel is also popular as a molding material for plastic injection molds.
