Premium 1.2080 Tool Steel Supplier for Unmatched Durability
1.2080 steel is a high-carbon, high-chromium tool steel known for its excellent wear resistance, hardness, and moderate corrosion resistance. When properly heat-treated, it achieves high hardness and good dimensional stability, making it ideal for applications like plastic molds, stamping dies, and cutting tools that require superior wear resistance. Easy to machine and heat-treat, 1.2080 steel is a versatile and widely used material in tooling applications.
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.

1.2080 heat treatment
1.2080 steel requires precise heat treatment to achieve its maximum hardness, wear resistance, and toughness. The quenching and tempering processes enhance these properties for cold work applications.
Quenching Process
Quenching involves heating the steel to a high temperature and rapid cooling to harden the material. For 1.2080 steel, the typical quenching procedure is as follows:
- Preheating: Heat the steel gradually to 600–800°C to reduce thermal shock.
- Austenitizing Temperature: Heat the steel to 950–980°C, transforming it into austenite (a high-temperature phase).
- Quenching Medium: Rapidly cool in oil or air for uniform hardness.
Recommended Quenching Process for 1.2080 tool steel
| Quenching Temperature (°C) | Cooling Medium | Hardness (HRC) |
|---|---|---|
| 950-980 | Oil | 59-63 |
This process ensures the steel hardens to its maximum potential.
Tempering Process
After quenching, the steel is hard but brittle. Tempering is required to reduce brittleness and improve toughness. The tempering process for 1.2080 is typically performed at 150–300°C, depending on the desired hardness. Higher tempering temperatures reduce hardness but increase toughness.
Typical Quenching and Tempering Data
| Process Step | Temperature (°C) | Time | Cooling Medium | Result |
|---|---|---|---|---|
| Preheating | 600–800 | 30 minutes | Air | Minimizes thermal shock |
| Austenitizing | 950–980 | 30–40 minutes | Oil or Air | Hardens steel |
| Quenching | 950–980 | Rapid cooling | Oil or Air | High hardness |
| Tempering (low) | 150–200 | 1–2 hours | Air | High hardness, lower toughness |
| Tempering (medium) | 200–300 | 1–2 hours | Air | Balanced hardness and toughness |
Hardness Values After Quenching and Tempering
| Tempering Temperature (°C) | Hardness (HRC) |
|---|---|
| 150 | 62–64 |
| 200 | 60–62 |
| 300 | 58–60 |
Recommended Tempering Process for 1.2080 tool steel
| Purpose | Tempering Temperature (°C) | Tempering Time (h) | Tempering Cycles | Hardness (HRC) |
