Material Description
1.2080 (X210Cr12 / AISI D3) is a high-carbon, high-chromium cold-work tool steel with excellent abrasive wear resistance due to its high chromium carbide content. It is commonly used for cutting dies, punches, shear blades and wear-resistant components. In the hardened condition (approximately 62 HRC), only specialized carbide cutting tools and geometries designed for hardened steels above 60 HRC are suitable. Due to the high concentration of hard chromium carbides, cutting tools are exposed to extremely high abrasive wear. Cutting parameters should therefore be significantly reduced compared to conventional hardened steels of similar hardness, and shorter tool life must be expected. Advanced coatings with high resistance to abrasive wear, such as TiSiN or other high-performance coatings, are strongly recommended to improve tool life.
