Grade: DIN 1.2210
Equivalent Steel: ASTM L2, ISO 115CrV3, JIS SKS43
DIN 1.2210 is a high-carbon cold work tool steel distinguished by its precise alloy chemistry, which delivers an optimal balance of wear resistance and toughness. With a carbon content ranging from 1.10% to 1.25%, it forms hard and stable carbides essential for resisting abrasive wear in cutting and forming tools. The addition of chromium (0.50-0.80%) enhances hardenability and contributes to carbide formation, while vanadium (0.07-0.12%) refines the grain structure, improving both toughness and edge retention. Manganese (0.20-0.40%) and silicon (0.15-0.30%) further support deoxidation and strength.

Qilu
DIN 1.2210 is a premium cold work tool steel compliant with DIN 17350. As a classic chromium-vanadium cold work tool steel, DIN 1.2210 and its international equivalent grades are formulated with a scientific alloy ratio of carbon, chromium and vanadium. Such as L2 from the American standard ASTM A681, 115CrV3 from International standard ISO 4957, and SKS43 from the Japanese standard JIS G4404. The formation of hard carbide phases in the microstructure endows the steel with excellent wear resistance, while the trace alloy elements optimize its toughness, effectively avoiding chipping and cracking during high-impact cold working processes.
This steel grade is widely adapted in international manufacturing systems, with each equivalent grade strictly following the national standard specifications while maintaining consistent core performance. It is suitable for various processing technologies such as forging, machining, heat treatment and surface finishing, and can be customized into bars, plates, blocks and other forms to meet the diverse needs of different industries.
The high carbon content (1.10-1.25% for DIN 1.2210) combines with chromium (0.5-0.8%) to form fine and uniformly distributed carbide particles in the steel matrix, which can effectively resist abrasive wear and adhesive wear during repetitive cold working operations. This performance makes it an ideal choice for tools and molds that require long-term continuous use without frequent replacement.
During the entire heat treatment process (annealing, quenching, tempering), the steel has a small thermal expansion coefficient and uniform tissue transformation, which can maintain tight dimensional tolerances. Even for precision molds and tools with complex structures, it can avoid deformation and size deviation caused by heat treatment, ensuring the accuracy of processed products.
Different from ordinary high-carbon steels that are brittle after hardening, DIN 1.2210 can reach a minimum hardness of HRC 60 after professional quenching and tempering, while retaining good impact toughness. It can withstand high impact loads in cold heading, stamping and other processes, effectively preventing tool and mold fracture and extending service life.
In the annealed state, the steel has a hardness of up to HB223, which is easy for turning, milling, drilling and other mechanical processing, and can be processed into complex-shaped workpieces with high precision. At the same time, it has good forgeability, and the blank can be formed by forging to improve the compactness of the material and enhance the comprehensive performance of the product.
All products pass strict ultrasonic testing in accordance with EN10228-3 Class III or Sep 1921-84 D/D standards, which can effectively detect internal defects such as inclusions and voids, ensuring the internal quality of the steel and avoiding early failure of tools and molds caused by internal defects during use.
DIN 1.2210 has corresponding equivalent grades in major industrial countries/regions, and the core performance is consistent while adapting to the respective national standard systems. The detailed equivalence table is as follows:
Country | USA | ISO | Germany | Japan |
Standard | ASTM A681 | ISO 4957 | DIN17350 | JIS G4404 |
Grade | L2 | 115CrV3 | 1.2210 | SKS43 |
Although the equivalent grades have the same cold work application positioning, there are slight differences in chemical composition due to different national standard formulation requirements, which lead to subtle performance differences, suitable for different sub-scenarios:
AISI L2 (USA): The carbon content range is wider (0.45-1.00%), the chromium content is higher (0.7-1.2%), and it contains a small amount of molybdenum (≤0.25%). It has better hardenability and is suitable for large-size cold work molds and tools that require deep hardening.
DIN 1.2210/115CrV3 (Germany/International): The carbon content is the highest (1.10-1.25%), the carbide content is more, the wear resistance is the best, and the dimensional stability is the most excellent. It is the first choice for high-precision and high-wear cold work scenarios such as precision stamping and deep drawing molds.
JIS SKS43 (Japan): The chemical composition is more moderate, the chromium content is lower (≤0.20%), the processing performance is better, and it is suitable for small and medium-sized precision tools, electronic connector blanking molds and small precision components with high processing accuracy requirements.
The chemical composition of each equivalent grade is strictly controlled in accordance with the respective standards, and the detailed components are as follows:
Grade | C | Si | Mn | P | S | Cr | Mo | V |
L2 | 0.45-1.00 | 0.10-0.50 | 0.10-0.90 | 0.030Max | 0.030Max | 0.70-1.20 | 0.25Max | 0.10-0.30 |
115CrV3/1.2210 | 1.10-1.25 | 0.15-0.30 | 0.20-0.40 | 0.030Max | 0.030Max | 0.50-0.80 | / | 0.07-0.12 |
SKS43 | 1.00-1.10 | 0.10-0.30 | 0.10-0.40 | 0.030Max | 0.030Max | 0.20Max | / | 0.10-0.20 |
Note: The content of harmful elements P and S is strictly controlled below 0.030%, which effectively improves the purity of the steel and avoids the reduction of toughness and processability caused by harmful inclusions.
The hardness of the steel changes with different heat treatment states, and the hardenability is excellent, which can meet the hardness requirements of different processing links and application scenarios:
Heat Treatment | Hardness |
Annealed (+A) | HB223 Max |
Cold-drawn condition | HB241 Max |

We adopt international advanced steel making processes to ensure the purity and uniform composition of the steel, and the optional processes include:
EF+LF+VD
EAF+LF+VD
EF+LF+VD+ESR
EAF+LF+VD+ESR
The secondary refining and vacuum degassing processes effectively reduce the content of gas and inclusions in the steel, and the electroslag remelting (ESR) process can further improve the compactness and uniformity of the steel ingot, making the material have better comprehensive mechanical properties.
Forging is the key link to improve the performance of DIN 1.2210 steel. We adopt the scientific forging process parameters to avoid material cracking and ensure the forging quality:
Preheating: Heat the steel to 500-550°C at a uniform speed to eliminate internal stress and reduce thermal stress during subsequent heating.
Forging temperature: Initial forging temperature 1050-1100°C, final forging temperature 850-900°C, to ensure the plastic deformation of the material and avoid overburning and underforging.
Cooling method: Sand cooling after forging, slow cooling to room temperature to avoid quenching cracks caused by rapid cooling and improve the toughness of the material.
The performance of DIN 1.2210 steel is highly dependent on the heat treatment process. We recommend the following standardized heat treatment process to ensure that the steel reaches the optimal performance index, and it can be adjusted according to the actual product size and application scenario:
Annealing is mainly used to reduce the hardness of the steel, improve the machinability, and eliminate the internal stress of forging and cold working:
Heat the steel to 760-780°C and keep it warm for a certain time according to the product size (1-2 hours per 50mm thickness).
Furnace cooling at a speed of ≤20°C/hour to about 600°C, then air cooling to room temperature.
After annealing, the steel has uniform microstructure and low hardness, which is suitable for various mechanical processing operations.
Quenching and tempering is the key process to obtain high hardness, high toughness and wear resistance of the steel, which is suitable for the finished mold and tool products:
Preheating: Preheat the steel to 649°C and keep it warm to ensure uniform heating of the material and avoid thermal shock during high-temperature heating.
Quenching heating: Heat to 870-890°C in a salt bath furnace and keep it warm (0.5-1 hour per 50mm thickness) to ensure complete austenitization of the steel.
Quenching cooling: Oil quenching cooling to room temperature to obtain martensite structure and improve the hardness of the steel.
Tempering: Temper the quenched steel at 204°C in a furnace and keep it warm for 2-3 hours, then air cooling to room temperature.
Effect: After quenching and tempering, the steel hardness reaches HRC60+, with balanced toughness and wear resistance, meeting the use requirements of cold work molds and tools.
The tempering temperature directly affects the hardness and toughness of the steel. For DIN 115CrV3 (1.2210) steel, the hardness shows a gradual downward trend with the increase of tempering temperature. It is recommended to control the tempering temperature within 200-300°C for cold work scenarios to ensure high hardness; for scenarios with higher impact toughness requirements, the tempering temperature can be appropriately increased (but not exceeding 400°C) to balance hardness and toughness.
Above curve in figure is a rough guide to the tempering behaviour of steels.
DIN 1.2210 and its equivalent grades are widely used in various cold work fields due to their excellent comprehensive performance, and the typical application scenarios are classified as follows:
