What is H13 Tool Steel?
H13 is a chromium-molybdenum-vanadium hot work tool steel designed to perform in extreme heat conditions. It is internationally standardized and available under multiple equivalents, such as:
- DIN 1.2344
- SKD61 (Japan)
- T20813
- X40CrMoV5-1
- WNR 1.2344
Because of its excellent heat resistance and toughness, Die Steel 1.2344 Round Bars are widely used in hot forging dies, pressure die casting tools, and extrusion dies.
Why H13 Steel Round Bar is So Popular
From real industry usage and customer feedback, here’s why H13 Steel Round Bar stands out:
1. Excellent Hot Strength: H13 retains its hardness and strength even at high temperatures, making it ideal for hot work tooling.
2. Superior Toughness: Compared to many other tool steels, H13 offers excellent impact resistance and crack resistance.
3. High Wear Resistance: The presence of chromium and vanadium improves wear resistance, increasing tool life.
4. Thermal Shock Resistance: H13 handles repeated heating and cooling cycles without cracking.
5. Good Machinability: Despite being a high-performance tool steel, H13 Round Bars can be machined efficiently using proper tools.
