T75Download T75 Spec sheet
WMT-75 is a chromium-molybdenum-cobalt hot work steel that has outstanding resistance to softening when tempering. As a result, it will withstand operating temperatures of approximately 50 to 75°F above those endured successfully by the 5% chromium hot work steels. It has very good thermal fatigue characteristics.
