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

     Sweden 20AP finished steel, lead small particles (<3μm), distribution, and its microstructure for the 3-4 grade granular pearlite, has been cutting good. The watch factory firm, is cutting more than similar steel imports from Japan is good.
