This specification covers the standard requirements for wrought low-carbon iron having a carbon content of 0.015% or less with the remainder of the analysis being substantially iron. Two alloy types are covered: Type 1 is a low-phosphorus grade and Type 2 contains a phosphorus addition to improve machinability. The alloy specimens shall conform to the required chemical compositions of carbon, manganese, silicon, phosphorus, sulfur, chromium, nickel, vanadium, titanium, aluminum and iron. The alloys shall be produced in a wide variety of forms and conditions namely: forging billet; hot-rolled product; cold-finished bars; strip; wire; and relay condition. The alloy materials shall undergo heat treatment. Magnetic testing shall also be performed wherein the alloys shall conform to the required values of the coercive field strength.
