This specification covers requirements for as cold-reduced, steel sheet in coils intended for conversion into cold-rolled steel sheet on continuous annealing lines, and metallic-coated steel sheet on continuous hot-dip coating lines. As cold-reduced steel sheet in coils comes in a semi-finished form and is produced to thickness requirements expressed to 0.001 in. (0.01 mm). Due to the high degree of cold reduction, as cold-reduced steel sheet exhibits high tensile strength with very minimal ductility.
This specification prescribes the requirements for chemical composition; mechanical properties; dimensions and mass; flatness, width, and coil size; product finish and condition; and packaging and marking.
