  Applications
  C10E Quenched and Tempered Steel equivalent to the C10 steel standardized according to UNI 7846/ 8550. It shows a limited tensile strength. It is destined to the manufacture of components subjected to wear, slightly stressed and with an easy geometry (pins, plugs, guides, boxes, bushings, sleeves, captive devices, ring nuts, shafts, hollow-shafts, gear wheels with a little module). It guarantees a high workability at the machines tools, high forgeability and formability. Advised austenitic grain dimension 5-8 according to UNI 3245 (similar to ASTM E 112-82).
