1.2379 - AT A GLANCE
What kind of steel is the 1.2379?
D2 Steel is a high carbon- and chromium steel with added alloys like molybdenum and vanadium. It is a high alloy, secondary-hardening, ledeburitic cold work steel. This high chromium steel is known for its low distortion and wear resistance and can also be found under the discription X153CrMoV12.
Properties
This Tool Steel and Plastic Mold Steel is often used when high wear resistance, tempering resistance and good ductility is needed. As well as the forementioned properties this steel presents high compression strength, good through-hardenability, high stability during hardening as well as an excellent cutting-edge retention.
- It is low-distortion
- It is wear-resistant
- It is through-hardenable
- It is pressure-resistant
- It is temper resistant
- It can be nitrided and eroded
- It is dimensionally stable
- PVD and CVD surface treatments is possible
- Black oxidizing the material is not possible
- Working hardness is a maximum of 62 HRC
Applications
1.2379 Tool Steel is a high-performance steel, often used for its hardness and wear resistance in many different areas, e.g., in several industrial sectors.
Here are a few examples:
- 1.2379 cutting and punching tools: Due to the high wear resistance and hardness, this steel is often used to manufacture punching and cutting tools (up to 25,5 mm). These include industrial knives, shears or cutting plates as well precision cutting tools up to 12 mm thickness.
- 1.2379 blanking and stamping tools: This steel grade is used for blanking and stamping tools as its properties make it a good choice for molds and dies.
- 1.2379 Plastic molds: For applications which need a high wear resistance like for example the production of plastic parts Premium 1.2379 is an excellent choice.
- 1.2379 Knives and blades: This steel grade is sometimes used for high quality blades but its hardness makes sharpening them difficult.
Specific examples of use:
- cutting tools
- fine blanking tools
- dies
- punches
- thread rolling dies
- thread rolling rolls
- broaches
- milling cutters
- hobs
- press tools
- woodworking tools
- shear blades
- deep-drawing tools
- cold rolling
- measuring tools
- cold pilger mandrels
- plastic moulds
