Cold pilger mandrels, circular-shear blades, deep-drawing tools. Pressure pads and highly resistant plastic moulds. Toughness better than D3.possibility of nitrating. 1.2080 Tools for cutting sheets up to 4mm thickness, trimming dies, blanking dies for paper and plastics, long and round-section shear blades for sheet thicknesses up to 2 mm, drawing and deep drawing tools. Woodworking tools, stone pressing tools, pressure pads and highly wear-resistant plastic moulds, profile rolls. 1.2510 Application include short run tooling for blanking dies, cold forming dies and cutting tools operating at ambient temperature. For working tools, cutting blazes, sizing and stamping tools. 1.2363 Blanking dies, rolls, shear blades, cold pilger mandrels, cold coining dies. Moulds for the processing of plastics. DC53 One fold toughness than SKD11, 520-530 C with 61-63 HRC to get rid of risk about cracking when processing, very suitable for surface hardening treatment to improve the longevity of moulds. 1.2357 Chisels, rivet sets, punches, driver bolts. Hot punching & shearing. 1.2550 For cutting tools(dyes, punches) for plate, wood working tools, blanking dyes for cutting sheet metals upto 12mm thickness., trimming & splitting dyes, shear blades, chipping knives, pneumatic chisels, coining tools, cold shear blades, ejectors.
