Grade: DIN 1.2080
Equivalent Steel: ASTM D3, ISO X210Cr12, GB Cr12, JIS SKD1
DIN 1.2080, globally recognized as AISI D3, is a high-carbon, high-chromium cold work tool steel whose exceptional performance is directly derived from its carefully balanced chemical composition. Defined by a high carbon content ranging from 1.90% to 2.20%, it generates a substantial volume of hard carbides within the steel matrix, providing the extreme wear resistance and high hardness—up to 62 HRC after heat treatment—required for demanding cutting and forming tools. This is complemented by a high chromium concentration of 11.00% to 12.00%, which not only contributes to the formation of these wear-resistant carbides but also enhances the steel's hardenability, ensuring consistent properties throughout the material's cross-section.

Qilu
DIN 1.2080 is a premium high-carbon high-chromium cold work tool steel engineered to meet the rigorous demands of high-stress manufacturing processes. Compliant with German DIN 17350 standards, this steel is celebrated for its exceptional wear resistance, stable dimensional performance, and high hardenability—making it the gold standard for precision cold working applications worldwide.
As a globally recognized grade, DIN 1.2080 has direct equivalent grades across major industrial standards, including the American standard D3 (ASTM A681), the international standard X210Cr12 (ISO 4957), the Japanese standard SKD1 (JIS G4404), and the Chinese standard Cr12 (GB/T 1299). This compatibility ensures seamless material sourcing for international manufacturing projects, eliminating supply chain barriers without compromising on performance. Whether for precision stamping dies, shear blades, or high-wear components, DIN 1.2080 delivers consistent, reliable results in the most demanding production environments.
With a carbon content of 1.90-2.20% and chromium content of 11.00-12.00%, DIN 1.2080 achieves a perfect balance of extreme hardness and wear resistance. High carbon content ensures superior edge retention for cutting and forming tools, while chromium forms fine carbide precipitates that enhance corrosion resistance and overall structural hardness—critical for tools subjected to repeated friction and pressure.
Heat treatment deformation rate of less than 0.1% ensures precise dimensional retention even under extreme cold working conditions. This stability minimizes post-processing costs and guarantees consistent part quality, making it the ideal choice for mass production molds and tools with tight tolerance requirements.
After professional hardening and tempering, DIN 1.2080 reaches a minimum hardness of HRC 62 (up to HRC 64 with optimized processes), capable of withstanding heavy loads and prolonged use in harsh working environments. Annealed hardness is controlled at HB248 max for easy machining, while cold-drawn condition maintains HB269 max for semi-finished components.
Produced via advanced steelmaking processes (EF+LF+VD / EAF+LF+VD / EF+LF+VD+ESR), DIN 1.2080 features uniform carbide distribution and minimal internal defects. All products pass EN10228-3 Class III / Sep 1921-84 D/D ultrasonic testing to ensure zero internal cracks, porosity, or inclusions—critical for high-precision mold applications.

DIN 1.2080 is manufactured via advanced processes to ensure uniform microstructure and consistent performance—critical for high-precision tool steel:
Basic Process: EF+LF+VD / EAF+LF+VD (for general applications)
Premium Process: EF+LF+VD+ESR (electroslag remelting, for high-precision molds with zero carbide segregation)
Strict temperature control to avoid carbide coarsening and internal defects:
Preheat ingot to 700-800℃ (slow heating to eliminate thermal stress)
Raise temperature to forging initial temperature: 1050-1100℃
Forge with final forging temperature ≥850-900℃ (no low-temperature forging to prevent cracks)
Cool in sand/lime (slow cooling to avoid internal stress and cracking)
Normalize and anneal after forging to optimize machinability
Proper heat treatment is critical to unlocking the full performance of DIN 1.2080. We provide standard and optimized processes for different applications, with key temperature and time controls to avoid common defects (e.g., overheating, temper brittleness):
Heating temperature: 820-850℃
Soaking time: 2-4 hours (based on material thickness: 1h/50mm)
Cooling method: Slow furnace cooling (≤10℃/h) to ≤200℃, then air cooling
Result: Uniform pearlite structure, HB248 max, excellent machinability
Preheating: 816℃ (one-stage preheating to avoid thermal shock)
Quenching Heating: 960-980℃ (salt bath furnace for uniform heating)
Soaking Time: 25±1 minutes (for test pieces; extend to 1-2min/mm for thick components)
Quenching Medium: Oil cooling (uniform cooling to avoid deformation/cracking)
Tempering: 170-190℃ for 60 minutes, air cooling after furnace removal
Result: HRC62-63, excellent wear resistance and dimensional stability
Add -196℃ deep cold treatment (2-4 hours) after quenching
Temper at 180-200℃ for 90 minutes (secondary tempering to eliminate residual stress)
Result: HRC63-64, reduced residual austenite, 20-30% improved wear resistance
Avoid overheating: Heating above 1000℃ causes carbide coarsening and reduced toughness
Prevent temper brittleness: Do not temper in the 250-400℃ range (irreversible low-temperature brittleness)
Thick components: Use step quenching to avoid internal soft spots
Electrical discharge machining (EDM): Perform stress relief tempering (180℃, 2h) after EDM to avoid cracking
Above curve in figure is just a rough guide to the tempering behaviour of steels. When applying the curves for an estimation of the hardness which can be expected in quenched and tempered tools, it should be taken into account that the optimum heat-treatment conditions for the tools are not necessarily identical with those specified for the test pieces.
The following table is for reference only—extend heating time by 50-100% for thick tools/components (>50mm):
Total heating time of test pieces in a salt bath
Nature of steel | Hardening Time min | Tempering Time min |
Cold or hot work steels | 25 +/- 1 | 60 |

DIN 1.2080 is not stocked for domestic Chinese use (due to low market demand). For customers in the Chinese market with similar performance requirements and budget constraints, we recommend Cr8 steel as a direct alternative:
Key Advantage: 30-40% lower cost than DIN 1.2080
Performance Similarity: Comparable wear resistance and hardness (HRC60-62 after heat treatment)
Ideal For: General cold work applications with non-critical tolerance requirements
Supply: In-stock availability for all standard sizes, fast delivery
A1: The primary difference lies in chromium content and wear mechanism. D3 has a higher carbon (2.00-2.35%) and chromium (11.00-13.50%) combination, leading to a higher volume of chromium carbides. This gives D3 superior abrasion wear resistance compared to D2. However, D2 (with ~12.00% Cr and additions of Mo/V) offers better toughness and corrosion resistance. Choose D3 for maximum wear resistance where toughness is less critical.
A2: To achieve a hardness of HRC 62+:
Preheat: Slowly heat to 816°C.
Austenitizing: Heat to 960-980°C in a controlled atmosphere or salt bath to prevent decarburization.
Quenching: Quench in oil or a salt bath at 500-550°C, then cool in air.
Tempering: Temper immediately after quenching to relieve stress. Temper at 170-190°C, holding for a minimum of 2 hours per inch of thickness, then air cool to room temperature.
A3: Yes, absolutely. We can supply all AISI D3 / DIN 1.2080 with EN 10204 3.1 mill test certificates, providing full traceability of the chemical composition and mechanical properties from the melt. Additional third-party inspections can also be arranged.
A4: Annealed: HB248 max (machinable); Cold-drawn: HB269 max; Hardened & tempered: HRC62 min (up to HRC64 with deep cold treatment).
A5: The core difference is in composition tolerance: DIN 1.2080 has stricter Si/Mn control (0.10-0.40%) and a narrower Cr range (11-12%), while AISI D3 allows V≤1.00% and a wider Cr range (11-13.5%). Performance is nearly identical for most applications.
A6: 1) Preheat before cutting/welding; 2) Avoid low-temperature forging (<850℃); 3) Perform stress relief tempering after EDM/grinding; 4) Use oil cooling (not water cooling) for quenching.
