Cold's selection of cold rolled steel, NBC 36-12I is a steel produced through the process of cold rolling. It is a lightly cold-rolled material with a thickness of 0.125 inches and a length of 36 inches. The I in the name stands for improved, which reflects its improved mechanical properties, such as formability, weldability, and surface finish, compared to other cold rolled steels. This steel is generally used to produce parts where dimensional accuracy, good surface finish, and uniformity of properties is desired. It is also often used in automotive, aircraft, and defense industries, particularly for components that need to be welded together.
