The chemical compositions of the materials are also established by the material specifications for each type or grade of material. The elements that are not identified should not be present in more than trace amounts except iron, of course, the primary constituent of carbon steels. The quality of carbon steel depend on the production quality process, some carbon steel from certain plant can have higher price than from other plant.
Single values are minimums unless otherwise identified, and ranges are given for other elements. The UNS number is listed again for convenience and because the main criteria used to establish that identification is the chemical composition.
