This specification covers 55% aluminum-zinc alloy-coated steel sheets in coils and cut lengths for applications requiring corrosion resistance or heat resistance or both. The material is available in several designations: commercial steel, forming steel, drawing steel, high temperature steel, and structural steel. Heat analysis shall be performed wherein the steel materials shall conform to the required chemical compositions of carbon, manganese, phosphorus, sulfur, aluminum, copper, nickel, chromium, molybdenum, vanadium, columbium, titanium, nitrogen and boron. Mechanical tests shall be performed wherein the steel sheets shall conform to the required values of yield strength, tensile strength and elongation. Triple-spot tests and single-spot tests shall also be performed and the materials shall conform to the required values of coating weight/mass. Steel specimens shall also undergo coating bend tests and shall conform to the required ratio of the inside bend diameter to thickness.
