Toolman Special Steels is proud to produce and offer 1.2601 steel. It is a Ledeburitic Cr-steel and corresponds to material number 1.2601 (X165CrMoV12). This alloy possesses a very high compressive strength and is deep hardening. 1.2601 steel is designed for high-performance cutting tools. It offers superior toughness compared to D3 steel and can be nitrided to enhance surface hardness and wear resistance.

HEAT TREATMENT AND PROCESSES
Heat treatment
| Process | Description | Temperature Range | Cooling Method | Resulting Hardness |
|---|---|---|---|---|
| Soft Annealing | Heating to 800-840°C followed by slow cooling in a furnace. This relieves internal stresses and produces a maximum Brinell hardness of 255. | 800-840°C | Slow furnace cooling | Maximum 255 Brinell |
| Stress Relieving | Heating to 650°C, holding for one hour, then air cooling. This process is done to relieve machining stresses and reduce distortion during heat treatment. | 650°C | Air cooling | - |
| Hardening | Heating to 980-1010°C followed by quenching in oil, air, or warm bath. This process increases hardness (63-65 HRC) by transforming the material's structure. | 980-1010°C | Oil, air, or warm bath quenching | 63-65 HRC |
| Tempering | Heating to 150-400°C. This process follows hardening and reduces brittleness, increasing toughness and ductility while maintaining some hardness | 150-400°C | - | - |

Frequently Asked Questions
We manufacture DIN 1.2601 / X165CrMoV12 as a ledeburitic chromium cold work tool steel with very high compressive strength and deep-hardening capability. It is designed for high-performance cutting and cold work applications where wear resistance is critical.
We position DIN 1.2601 where higher toughness than D3 is required. It also offers strong wear resistance and compressive strength and can be nitrided where additional surface hardness and wear resistance are needed.
We supply DIN 1.2601 for:
- Machine knives
- Cold-forming and rolling tools
- Fine blanking and stamping tools
- Moulds, plates, pins and punches
- Recycling-industry components
- Cutting and woodworking tools
- Drawing and deep-drawing tools
- Pressing tools
- Cold-working rolls
- Measuring tools
Our heat-treatment guidance includes:
- Soft annealing: 800–840°C
- Stress relieving: 650°C
- Hardening: 980–1010°C
