DIN 1.2344 / AISI H13 Tool Steel – The Hot Work Champion for Die Casting, Extrusion & Molds
In the world of metal shaping, there’s no room for weak links. Your die steel has to take the heat (literally), hold its shape, and keep on punching day after day. Enter: DIN 1.2344, also known as AISI H13.
It’s not just another steel grade – it’s the reliable workhorse of hot work applications. And at Toolman Special Steels, we’ve been proudly supplying this powerhouse to die-makers and toolrooms across USA, Europe, Japan, Turkey, and Southeast Asia for years. If you're on the hunt for a DIN 2344 hot work steel manufacturer who actually gets what high-performance steel needs to do, keep reading.
What Makes DIN 2344 So Damn Good?
This chromium-molybdenum-vanadium steel has all the right elements for thermal resilience, toughness and long-term strength under heat-stress environments. It offers:
- Excellent thermal shock resistance
- Red hardness up to 600°C
- Great wear resistance under pressure
- Superb polishability for complex moulds
It’s basically engineered for hot work specialities: think aluminium/zinc die-casting dies, plastic moulds, extrusion dies, and hot forging tools.
DIN 1.2344 / H13 - Chemical Composition
| Element | Content (%) |
|---|---|
| C | 0.32–0.45 |
| Cr | 4.75–5.50 |
| Mo | 1.10–1.75 |
| V | 0.80–1.20 |
| Si | 0.80–1.20 |
| Mn | 0.20–0.50 |
It's a well-balanced group that keeps your die stable and hard even under serious thermal variations.
Where It Works Best
If your parts touch high temperatures, impact, or abrasion regularly – this is your steel:
- High-pressure die casting dies
- Plastic injection moulds
- Hot extrusion tools
- Forging dies and shear blades
It’s even used in die holders and inserts for automated press systems.
