Breaking Through Strict Tolerances – Delivery Record of 200 Tons of C67 Alloy Cold Rolled Steel Strip to the European Market
To meet the maximum 190 HV hardness and excellent 180-degree bending performance, the technical team redesigned the spheroidizing annealing process curve. By precisely controlling the heating temperature, holding time, and cooling rate, we not only eliminated the work hardening caused by cold rolling but also achieved uniform spheroidization of carbides.
