1.1 This specification covers carbon steel bars and shapes produced from standard rail steel. These bars are furnished in the as-wrought condition intended for structural use, or bar and shape uses, where high tensile properties are applicable. These materials are available in two strength levels as Grades 50 and 60.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.


This specification covers the standard for carbon steel bars and shapes rolled from standard rail steel. The material shall be hot wrought from section T rails and shall be produced by hot forming slit railroad rail parts to yield straight lengths. One tension test and one hardness test shall be performed from each lot to determine the mechanical properties and shall conform to the requirement in tensile strength, elongation, Brinell hardness, and Rockwell B hardness.
