Annotation

This specification deals with carbon steel girder rails of plain, grooved, and guard types. Materials considered in this specification are grouped into three classes (Class A, B, and C) based on type, weight and chemistry (carbon, manganese, phosphorus, and silicon compositions). Steel samples shall be melt processed by either open-hearth, basic-oxygen, or electric furnace, and may be cast by a continuous process or in ingots. Material specimens shall undergo product analysis and tests, and shall conform to required chemical and physical attributes such as chemical composition, Brinell hardness, weight, length, sectioning, end finishing, drilling and punching specifications. Rails shall be finished by cold straightening in a press or roller machine to remove twists, waves and kinks. Final products shall be marked either by brand and stamp, paint, or bar code.
