ST12 cold rolled steel sheet is a common cold rolled product that belongs to the German standard DIN1623, equivalent to EN10130's DC01, JIS's SPCC, American standard ASTM A1008 CS, and Q/BQB 403 DC01.
ST12 is a common cold rolled steel that features a low carbon content, which makes it highly plastic and ductile, easy to shape and make into different products. The cold rolling process gives ST12 steel a smooth surface finish, enhancing its aesthetics and corrosion resistance. The surface quality of this steel can be divided into FC-high-grade finishing surface and FB-higher-grade finishing surface. In addition, ST12 steel has excellent welding and machining characteristics, suitable for a variety of manufacturing processes.
