EX1 Victory ESR 1.2367 MOD Modified hot work tool steel with excellent toughness and improved hot strength with high Mo content. Material Properties Excellent toughness and ductility. Very good thermal checking. Thermal shock resistance. Very good hot strength and tempering back resistance. Good weldability. Good machinability. Recommended working hardness 40-50 HRc. Good coating and nitriding ability. Certificate Highly certified grade, and many properties’ quality is guaranteed by the certifying supplier company such as toughness, microstructure cleanness and many more. Applications Long life die casting dies, cores and cavities. Die casting dies: On visual sections where heat checking / thermal fatigue occurred Against to cracking, total failure, gross checking risks Against to tough operating conditions due to thermal shock If the wall thickness of the Al part is very thin or very thick Dies with complex geometry. If it is very cosmetic Al part PVD coated insert against to soldering. Cores in press forging die. Press forging dies where high toughness is required. Preferred for dies and molds subjected to high temperatures and the risk to breaking or cracking. Blades, punches thicker than 10 mm in cutting and shearing dies. Cold forging, cold extrusion dies.
