Toolman Special Steels is proud to produce and offer 1.2367 steel, also known as X38CrMoV5-3, is a high-performance hot work tool steel with excellent toughness and resistance to thermal fatigue. It is widely used for hot work applications where high mechanical strength and wear resistance are essential. It has been refined via ESR process to ensure highest quality standards in terms of grain size, segregation, micro-cleanliness, and purity. EN DIN 1.2367 features high isotropy, reason for which transversal resilience is often three times higher when compared to conventional EN DIN 1.2367. Furthermore, the thermal fatigue resistance is also often much higher than that of conventional hot work tool steel EN DIN 1.2343, enabling longer die lifetime.
