Requirements for weldability are contained in the annex (Annex X6) of the ASTM A6/A3M standard.Ī36 steel is a commonly used structural steel in the USA. Such requirements apply if specified in the purchase order.Īlso, if steel welding is required during the use of the material, a welding procedure appropriate to the steel grade and the intended use or service should be used. The full name of the standard in question is: ASTM A36 /A36M-19 standard specification for carbon structural steel.Īdditional requirements are provided in the ASTM A36 standard for use where other testing or additional restrictions are required by the purchaser. In this regard, the material must comply with the required tensile properties. Tensile strength, yield strength and elongation properties are evaluated using the tensile test. This standard provides a heat analysis method to determine the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon and copper. Developed by the American Society for Testing and Materials (ASTM), the ASTM A36 standard includes structural steel shapes, plates and bars for use in riveted, bolted or welded construction of bridges and buildings and for general structural purposes.
