1.2080 is a high-carbon, high-chromium tool steel that conforms to the German standard DIN 17350. It is renowned for its exceptional wear resistance, high hardness, and good dimensional stability, making it suitable for applications requiring durability and precision under high-stress conditions. Due to its outstanding performance, many countries have developed equivalent steels to DIN 1.2080. Such as 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).

DIN 1.2080 is a premium high-carbon, high-chromium cold work tool steel that adheres to the German standard DIN 17350. Renowned for its exceptional wear resistance, outstanding hardness, and reliable dimensional stability, this steel is engineered to excel in high-stress applications where durability and precision are non-negotiable. It has been widely recognized globally, with equivalent grades across major standards—including AISI D3 (ASTM A681), X210Cr12 (ISO 4957), JIS SKD1 (JIS G4404), and Chinese Cr12 (GB/T 1299)—making it a versatile choice for international manufacturing projects. Whether used in blanking dies, shear blades, or high-precision components, DIN 1.2080 delivers consistent performance that meets the demands of rigorous cold working processes.
With a carbon content ranging from 1.90-2.20% and chromium levels of 11.00-12.00%, DIN 1.2080 achieves an optimal balance of hardness and wear resistance. The high carbon content ensures superior edge retention, while chromium enhances corrosion resistance and overall hardness—critical properties for tools subjected to repeated friction and pressure.
Even under demanding cold working conditions, DIN 1.2080 maintains precise dimensions, minimizing post-processing efforts and ensuring consistent part quality. This stability is particularly valuable for molds and tools that require tight tolerances for mass production.
The availability of equivalent grades (AISI D3, X210Cr12, JIS SKD1, Cr12) allows manufacturers to source materials seamlessly across regions, ensuring supply chain flexibility without compromising performance.
After hardening and tempering, DIN 1.2080 reaches a minimum hardness of HRC 62, making it capable of withstanding heavy loads and prolonged use in harsh working environments.
