1.What is A573/A573M carbon steel plate standard?
This specification covers structural quality carbon-manganese-silicon steel plates in three tensile strength ranges intended primarily for service at atmospheric temperatures where improved notch toughness is important. If the steel is to be welded, a welding procedure suitable for the grade of steel and intended use or service shall be utilized. The steel shall be made by fine grain practice. Heat and product analysis shall conform to the chemical composition requirements prescribed for carbon, manganese, phosphorus, sulfur, and silicon. The tension test specimen shall conform to the tensile requirements including tensile strength, yield point, and elongation.ASTM A573/A573M grades are divided into: 58, 65, 70, and the steel plates are suitable for structural grade carbon-manganese-silicon steel plates in three tensile strength ranges. ASTM A573/A573M steel plates are mainly used for important purposes of improving notch toughness at room temperature.
