Hot work tool steels - BÖHLER W-grades

Generally the term "hot work steel" includes tool steels which adopt a constant temperature of above 200ºC (392ºF) during application. Superimposed on the latter are peak temperatures brought about by the operational cycle. Consequently, the use of hot work steels involves, in addition to the usual stresses which tool steels are subjected to, thermal stresses due to the contact between tools and hot materials during forming. For detailed information on the hot work tool steel grades please refer to "Brochures".
