H13 (1.2344) Tool Steel

h13-1-2344-tool-steel-product-image

H13 tool steel (1.2344 H13) is a high performance hot work tool steel known for its toughness, thermal fatigue resistance, and wear resistance at elevated temperatures. It is ideal for demanding tooling applications in industries like aerospace, automotive, and industrial manufacturing.

Key Features

AISI H13 delivers a strong combination of high hot hardness, excellent machinability, and polishability. Its stability under thermal cycling and heavy loads makes it a reliable choice for die casting, extrusion, hot forging, and other high stress hot work tooling.

Typical Applications
  • Die-casting dies for aluminium, magnesium, and zinc alloys
  • Extrusion tooling and hot shear blades
  • Hot forging and hot punching dies
  • Plastic moulds requiring high polish and thermal resistance
  • Thermal fatigue resistant tools for aerospace and automotive production
Forms of Supply

Supplied in annealed or pre hardened condition as round bars, plates, flats, and blocks. Available in full lengths or custom cut sizes, with delivery across the UAE, Oman, and the Gulf region.

H13 tool steel (1.2344 H13) delivers premium hot work performance under extreme heat and heavy loads. Its toughness, thermal fatigue resistance, and wear resistance support precise tooling and reliable operation across long production cycles. Industrial metal suppliers in the UAE rely on this grade for consistent quality and high performance.

 

This steel also offers excellent machinability and polishability, enabling high finish dies and moulds to retain dimensional stability even during repeated thermal cycling. As trusted H13 tool steel traders and tool and die steel suppliers, we supply to our customers across Saudi Arabia and the wider GCC. It is widely used in aerospace, automotive, and industrial sectors for tooling that demands strength, heat resistance, and durability.

Key Advantages of H13 Steel
  • Outstanding toughness and high temperature wear resistance
  • Maintains dimensional stability under thermal cycling and heavy loads
  • Excellent machinability and polishability for precision tooling
  • Ideal for die casting, extrusion, and hot forging applications

Technical Specifications

Chemical Composition
  • Carbon (C): 0.32 – 0.45% – Provides base strength and contributes to hot hardness.
  • Silicon (Si): 0.80 – 1.20% – Enhances strength and thermal stability.
  • Manganese (Mn): 0.20 – 0.50% – Improves toughness and deoxidation.
  • Chromium (Cr): 4.75 – 5.50% – Increases hardenability and wear resistance at elevated temperature.
  • Molybdenum (Mo): 1.10 – 1.75% – Boosts high-temperature strength and creep resistance.
  • Vanadium (V): 0.80 – 1.20% – Refines grain and enhances toughness and thermal fatigue resistance.
  • Phosphorus (P): ≤ 0.03% – Limits brittleness and ensures soundness.
  • Sulfur (S): ≤ 0.03% – Maintains quality and machinability.
Treatment
  • Annealing: Heat slowly to ~750-780 °C, soak thoroughly, then furnace-cool to achieve approx. ≤235 HB for machining.
  • Hardening: Austenitise around 1000-1050 °C (depending on section size) then quench in oil or air to ensure deep hardening.
  • Tempering: Typically temper at 550-650 °C (or higher) depending on required balance of hardness and toughness; multiple temper cycles recommended.
  • Finish Machining & Polishing: Excellent polishability makes H13 ideal for high-finish moulds and tools subject to thermal shock.
