DIN 1.2080 steel contains 2.1% carbon and more than 11% chromium alloy, which is defined as high carbon and high chromium cold work tool steel as per DIN 17350 standard.
As one of the classic representative steels of cold work tool steel, DIN 1.2080 steel has the characteristics of high strength, high toughness, high hardness, high hardenability, excellent wear resistance and good processing performance.
DIN 1.2080/X210Cr12 steel is usually delivered in annealed condition with hardness below 248HBW.
