This specification covers hot-wrought steel bars for the manufacture of general purpose springs such as coil, torsion, and leaf. The steel shall be melt processed by using open-hearth, basic-oxygen, or electric furnace. The materials shall undergo heat analysis and shall conform to the required chemical compositions and hardenability. The steel specimens shall conform to the required values of rounded corner radii and cross section tolerances for round-edge flat bars.
