    Cold-drawn round steel bars

    n

    Trafilerie Assi, specializing for more than 40 years in the cold drawing industry, produces cold-drawn round steel bars.

    The product range is divided into: steels not intended for heat treatment, 11SMnPb30 and 11SMnPb37, and steels for 36SMnPb14 direct hardening.

    Round steel bars table according to UNI EN 10277-1-3:

    Symbolic designation Diameter range
    11SMnPb37+C 2 – 90mm
    11SMnPb30+C 8 – 90mm
    36SMnPb14+C 4 – 56mm
    11SMnPb37+Te+Bi+C 4 – 17mm
    11SMnPb37CX+C 2 – 65mm

    Items that are not included in this prospectus should not be intentionally added to steel without the consent of the customer, except for the purpose of refining the cast. The elements such as Te, Bi, etc., may, however, be added by the manufacturer to improve workability, if this has been agreed at the time of offer and order.
