1.2083 steel state of deliver is softening, annealing, the hardness 215~240HBW. Has a good corrosion resistance, abrasion resistance, hardenability, and cutting. Its low impurity content, due to the excellent resistance to corrosion, maintenance costs arerelatively low, high surface accuracy, long-term production can still hold the originalhigh–precision.
