Size: Round: 8-300 mm Flate: 12-90*205-305 mm Chemical composition%(for reference): C Si Mn Cr 2.00-2.30 0.40 0.40 11.50-13.00 Delivery condition: Soften annealed:255HB Application: Cr12 steel has excellent wear-resisting performance. It is mainly used for long-life punching die, blanking die, drawing die, press rolling die, edge rolling die that are designed for processing the sheet metal with thickness not greater than 2 mm, and is also widely used for ceramic dies. It is also used for making various scissors, crushing cutters for waste plastics, etc. Features: Cr12 steel is a high-carbon and high-chromium alloy tool steel. It features good size stability after heat treatment, strong hardenability, high quenching hardness and high compressive strength. It is suitable for making the high-precision and long-life cold work dies.
