H13 Hot Die Steel Applications, Suppliers, Price, Chemical Composition and Key Information.
H13 hot die steel is a versatile tool steel known for its excellent toughness, heat resistance, and wear resistance.
It is widely used in hot work applications, where tools and dies are exposed to extreme temperatures and mechanical stress.
H13 belongs to the AISI H-series of tool steels, with a high chromium-molybdenum composition that enhances its durability.
Key Properties of H13 Hot Die Steel
- High Heat Resistance – Retains strength and hardness at elevated temperatures.
- Excellent Toughness – Resists cracking and chipping under thermal and mechanical stress.
- Wear and Abrasion Resistance – Performs well in demanding environments.
- Good Machinability – Can be cut, shaped, and polished with ease.
- Air-Hardening Steel – Reduces the risk of distortion and cracking during heat treatment.
Chemical Composition of H13 Steel
| Element | Percentage (%) |
|---|---|
| Carbon (C) | 0.32 – 0.45 |
| Chromium (Cr) | 4.75 – 5.50 |
| Molybdenum (Mo) | 1.10 – 1.75 |
| Vanadium (V) | 0.80 – 1.20 |
| Silicon (Si) | 0.80 – 1.20 |
| Manganese (Mn) | 0.20 – 0.50 |
These elements contribute to high-temperature strength, wear resistance, and toughness.
