This specification covers hot-wrought and cold-finished special quality carbon steel bars, in straight lengths only, subject to mechanical property requirements and intended for use in manufacturing components for pressure piping and other pressure-containing applications. The steel bars are furnished in Grade B and Grade C and shall be made by melting, deoxidation, hot and cold working, heat treatment, and shall have special quality. Heat and product analyses shall be performed on the material and the chemical composition shall conform to the values required in carbon, manganese, phosphorus, sulfur, silicon, and lead. The carbon steel shall undergo tensile testing and conform to the required tensile strength, yield strength, and elongation.
