Unflinching in Heat, Uncompromised Performance: H13’s core advantage lies in its exceptional thermal stability and heat resistance. Even under sustained operating temperatures of up to 600°C, it maintains outstanding hardness and wear resistance, effectively countering softening and deformation caused by heat. This ensures consistent dimensional accuracy of the final product.
Exceptional Toughness, Crack Resistance: H13’s remarkable toughness endows it with superior resistance to thermal fatigue and impact stress. Under cyclic thermal shock conditions (e.g., die casting, forging), it effectively resists the initiation and propagation of thermal stress cracks, significantly extending mould service life and reducing unplanned downtime risks.
Exceptional Wear Resistance, Enduring Performance: Coupled with outstanding wear resistance, H13 moulds endure prolonged exposure to the erosion and friction of molten metals or high-strength materials. This maintains cavity smoothness, reduces reworking frequency, and ensures stable output of product surface quality.
Superior Quenchability with Balanced Properties: Excellent hardenability ensures uniform performance across large-section moulds, eliminating concerns over soft spots. Concurrently, its relatively stable heat treatment process facilitates the attainment of ideal hardness and microstructure, simplifying production preparation.
