1.1 This specification covers sheet steel in coils and cut lengths for porcelain enameling. The compositions and processing of these steels are such that articles for porcelain enameling may be fabricated from them and, under proper conditions, enameled. The steels are furnished as Type I, Type II, and Type III. Type I and Type II are supplied in two designations, Commercial Steel and Drawing Steel. Type III steel is interstitial-free and does not require a designation.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.3 Tolerances are found in General Requirements Specifications A 568/A 568M
