This specification covers deformed and plain carbon-steel bars for concrete reinforcements in cut lengths and coils. Materials considered under this specification are available in Grades 40 [280], 60 [420] and 75 [520]. Steel samples shall be rolled from properly identified heats of mold cast or strand cast steel using electric-furnace, basic-oxygen, or open-hearth. Heat analysis shall be performed wherein steel materials shall conform to required compositions of carbon, manganese, phosphorus and sulfur. Steel specimens shall also undergo tensile tests and shall conform to required values of tensile strength, yield strength, and elongation. Steel samples shall also undergo deformation test, tension test and bend tests. Final products shall be marked by a tag. This abstract is a brief summary of the referenced standard.
