X38CrMoV5-3
1.2367Premium hot work tool steel — higher Mo (2.7-3.2%) than H13/1.2344 (1.1-1.5%) for superior hot strength and temper resistance. Better thermal fatigue life in demanding die casting. Often specified for aluminum high-pressure die casting where H13 life is insufficient. Used for Al/Mg die casting dies, hot forging dies, and extrusion tools requiring longer life than H13.
