Anotation

This specification covers standards for hot-wrought, special quality microalloyed carbon steel bars intended for use in applications where as-rolled mechanical properties are desired. A typical end use includes hydraulic cylinder shafts. The typical chemical composition of microalloyed carbon steel shall contain carbon, manganese, phosphorus, sulfur, and vanadium. Heat and product analyses shall be conducted wherein the material shall conform to the required chemical composition for vanadium, columbium (niobium), and molybdenum. The elements and specified chemical ranges shall not exceed the required limits. The steel bars shall undergo tension test and conform to the mechanical property requirements such as yield strength, tensile strength, and elongation.
