ASTM A366 describes
cold rolled carbon steel of commercial quality. ASTM A569 designates hot rolled carbon steel sheet and strip of commercial quality, in coils and cut lengths, with a maximum carbon content of 0.15%.
These steels are used for products produced by bending, moderate forming, and welding.
1. Scope
1.1 This specification covers
cold-rolled carbon commercial steel (CS) sheet, in coils or cut lengths. This material is intended for exposed or unexposed parts where bending, moderate drawing, forming, and welding may be involved.
1.2 This specification is not applicable to Specification A 109. Narrow widths multiple slit from wide sheet are not strip, unless they qualify as strip because of thickness, special finish, special edge, or special temper.
1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
