Hot rolled coils with middle and high carbon content serve as the primary raw material. To produce strips with the desired breadth for hot rolling, the coils are slit on a slitting machine. These hot rolled pieces are acid pickled for scale removal through a continuous pickling line after being slit. Depending on the desired final thickness, the rolling and intermediate annealing processes can be done as many times as necessary for medium- and high-carbon coils. After their final rolling, these coils are slit on a CR slitting machine to achieve the desired end width. The Hardening/Tempering section receives these cold-rolled and slit coils for additional processing.

Strips are heated in an electrically heated furnace in an airtight muffle in an inert environment, then quenched and tempered to the required hardness. Next, the pieces are edge dressed. (if desired). The grey segments from the H/T line are polished with a buffing compound or ground to a bright finish. The strips can also be colored and tempered to achieve the desired hue (blue, yellow, bronze, or golden), and they are then examined, oiled, and packaged for shipment.
