H13 Tool Steel / DIN 1.2344 / JIS SKD61 / GOST 4Х5МФ1С

With these formidable properties, H13 tool steel has permeated numerous critical manufacturing processes, becoming the unsung hero of efficient production:

The Mainstay of Die Casting: H13 is extensively employed in core components (such as cores, cavities, and slides) for aluminium, magnesium, and zinc alloy die casting moulds. Withstanding the corrosive effects of molten metal at high temperatures, it forms the cornerstone for ensuring die-cast part quality and production efficiency.

A Solid Backbone for Forging Operations: Forging hammers, punches, and hot extrusion dies (for copper, aluminium, etc.) endure immense impact forces during high-temperature forging. H13’s exceptional high-temperature strength and toughness make it a dependable choice.

Reliable assurance for precision hot forming: H13 also excels in mould applications requiring high precision and stability, such as hot stamping and hot shearing.

The preferred choice for general-purpose hot-work moulds: H13 is frequently selected for various plastic moulds operating at elevated temperatures (particularly those for high glass-fibre reinforced materials) and thermoset plastic moulding dies.

Our Advantages in Processing H13 Tool Steel

Fully recognising the decisive impact of mould material quality on your production efficiency, we implement stringent end-to-end quality control throughout H13 tool steel production:

Source Control – Pure Molten Steel: Utilising advanced electroslag remelting or vacuum arc remelting processes, we maximally eliminate harmful gases (oxygen, hydrogen, nitrogen) and non-metallic inclusions from the steel, significantly enhancing purity, density, and toughness.

Homogeneous Density – Forging Optimisation:

Employing multi-directional forging or precision rolling techniques, we thoroughly refine grain structure and eliminate casting defects. This ensures uniform material properties across all three dimensions, reduces anisotropy, and enhances overall mould reliability.

Precision Calibration – The Art of Heat Treatment:

We meticulously control temperature, duration, and cooling rates during critical processes like annealing, quenching, and tempering. Particularly through refined tempering processes, we achieve an optimal balance between secondary hardening effects and superior toughness, maximising the performance potential of H13 steel.

End-to-End Protection – Non-Destructive Testing: Each batch undergoes ultrasonic testing and other non-destructive inspections to rigorously screen for internal defects (such as cracks, inclusions, and white spots), ensuring every delivered piece of H13 material meets internal structural integrity requirements.

Consistent Reliability – Batch Consistency: Through stringent chemical composition control and standardised production processes, we guarantee highly stable performance across different batches of H13 steel, providing you with predictable mould life and production planning assurance.
