Aobo Steel supply 1.2344 steel for your project
Premium 1.2344 Tool Steel Supplier for Unmatched Durability
1.2344 tool steel, also known as H13 tool steel, is a versatile, high-performance steel used in various industrial applications. Known for its toughness, heat resistance, and ability to withstand thermal fatigue, it is a top choice for hot-work tool applications such as die casting, extrusion, and forging.
Most cost-effective, high-quality supplier of D2 steel
We offer both D2 electric furnace steel and D2 ESR steel. Considering our customers’ purchasing costs, we produce D2 round bars with diameters under 200mm using the electric furnace method, which can meet Ultrasonic testing (UT) Sep 1921-84 D/d flaw detection. Customers can purchase high-standard D2 round bars at a lower cost. We adopt the ESR process for diameters above 200mm to ensure that the internal structure can meet Ultrasonic testing (UT) Sep 1921-84 E/e flaw detection.
Excellent D2 Forged Steel Supplier
Aobo Steel has over 20 years of experience in forging D2 steel, giving us a deep practical understanding of quality control in this field. Our D2 forged steel products mainly come in round bar, plate, and block shapes. We have over 40 suppliers providing the best processing services, enabling us to offer advantages such as short lead times, stable quality, and competitive prices.

Machinability and Weldability
Machinability: 1.2344 tool steel has moderate machinability and is best machined in its annealed condition. Proper cutting fluids and tools should be used to reduce tool wear.
Weldability: Welding 1.2344 can be challenging, requiring careful preheating and post-weld heat treatment to avoid cracking. Special welding techniques are recommended to maintain weld integrity.
Heat Treatment Process
| Step | Temperature Range | Process | Purpose |
|---|---|---|---|
| Annealing | 820°C – 860°C (1508°F – 1580°F) | Heat the steel, hold it for a suitable time, and then cool it slowly in the furnace. | Softens the material, making it easier to machine. |
| Hardening | 1000°C – 1050°C (1832°F – 1922°F) | Heat the material, hold it for uniform heating, then quench it in air or oil. | Increases the hardness and strength of the steel. |
| Tempering | 540°C – 650°C (1004°F – 1202°F) | Reheat the steel after hardening, depending on the desired hardness. | Enhances toughness while reducing brittleness. |
1.2344 Applications
Due to its excellent combination of heat, toughness, and wear resistance, 1.2344 tool steel is widely used in industries with prevalent hot-working and high-stress applications. Some common applications include:
Die Casting Dies: 1.2344 is commonly used in aluminum, zinc, and magnesium die-casting molds, where resistance to thermal fatigue and mechanical strength are critical.
Forging Dies: The high toughness and thermal stability of 1.2344 make it ideal for creating forging dies, which must withstand extreme pressure and heat.
Extrusion Tools: 1.2344 is widely used in extrusion dies for metals and plastics, where the steel’s wear resistance and thermal stability ensure a long service life.
Hot Shear Blades: Blades used for cutting hot metals benefit from 1.2344’s heat resistance and durability, making it a preferred choice in high-temperature cutting applications.
Plastic Molding: In the plastic molding industry, 1.2344 is used in molds that require resistance to thermal and mechanical fatigue during high-pressure injection molding processes.
