DESCRIPTION: Mild steels are low carbon variants with carbon levels of up to 0.12%, with such grades as SPCC, SPCD, SPCE and SPCF. It can only be hardened by cold working. Such Mild Steel Strip has relatively low tensile strength but good ductility levels which facilitate the production of complicated component shapes where required and even allowing deep pressing processes to be carried out.
APPLICATIONS: Flexible hose, Pressings, Banding for electrical cable ties, off shore gas/oil, signage and packing, Electronic components, Tube strip, Automotive exhaust and trim etc.
