This specification covers hot-wrought merchant quality carbon steel bars and bar size shapes produced to mechanical property requirements and intended for noncritical constructional applications. The bars shall be available in round, square and hexagonal shapes. The steel shall be made by the open-hearth, basic-oxygen, or electric-furnace process. The specimens shall undergo a tension test to determine tensile strength, yield point and elongation. The merchant quality bars shall be from visible pipe; however, they may contain pronounced chemical segregation. Internal porosity, surface seams, and other surface irregularities may be present in this quality. The bars shall also be furnished as rolled and not pickled, blast cleaned, or oiled.
