Hot Work Tool Steel
H10/DIN 1.2365 / AISI H10/4Cr3Mo3SIV
H10 is a chromium hot work tool steel engineered for high-temperature strength and toughness. It resists thermal fatigue and heat checking through repeated heating and cooling cycles. The grade maintains hardness and strength at elevated temperatures to keep tools stable under load. Its balanced alloy design supports reliable machinability and consistent heat treatment response. H10 is widely used for die casting dies, hot extrusion tooling, and forging dies. It performs well in hot shear blades, mandrels, and punches where shock resistance matters. Built for long service life, H10 helps reduce downtime in severe hot work applications.
