Cold-drawn square steel bars

n

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

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

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.
