ASTM A424 is officially known as the standard specification for steel, sheet, and porcelain enameling. The specification goes on to say “ This specification covers standard requirements for sheet steel in coils and cut lengths for porcelain enameling. Heat analysis of Type I, Type II, and Type III steels shall conform to the prescribed chemical composition for carbon, manganese, phosphorus, sulfur, and others. However, an exception is made on carbon, since heat analysis of carbon is not appropriate for Type I. The material shall also conform to the required mechanical properties such as bending and formability ”.
