    Sweden 20AP-cutting just

        Chemical composition:

    C 0.95-1.05, Si ≤ 0.30, Mn0.25-0.50, S 0.035-0.055, P ≤ 0.035, Pb 0.15-0.25

         Rui is a lead single 20AP Gauteng carbon free cutting steel, is to create precision watch parts one of the important material. 20AP is widely used in high precision grinding rod axis parts, especially for higher surface hardness after heat treatment of thin pieces so small shaft
