标准范围
This International Standard applies to cold-reduced steel sheet of structural quality in grades CR220, CR250,CR320 and CH550, usually without the use of microalloying elements. The product is intended for structuresthat may include bolting, riveting and welding. It is generally used in the delivered condition for fabricatingpurposes, such as bending, forming or welding.This product is commonly produced in thicknesses from 0,36 mm up to 3 mm and in widths of 600 mm andover, in coils and cut lengths.Cold-reduced sheet less than 600 mm wide may be slit from wide sheet and will be considered as sheet.This International Standard does not cover steels designated as commercial quality or drawing qualities(covered in ISO 3574), cold-reduced carbon steel sheet according to hardness requirements (covered inISO 5954), cold-reduced steel sheet of higher strength with improved formability (covered in ISO 13887), orcold-reduced steel sheet of high tensile strength and low yield point with improved formability (covered inISO 14590).
