The A283/A283M-13 steel grade is a standard specification for low and intermediate tensile strength carbon steel plates. It is commonly used in the construction industry for structural applications.
The chemical composition of A283/A283M-13 steel grade includes carbon, manganese, phosphorus, sulfur, silicon, and copper. The carbon content provides strength and hardness to the steel, while manganese enhances its toughness and ductility. Phosphorus and sulfur are impurities that should be kept to low levels, as they can negatively affect the steel’s mechanical properties. Silicon and copper are added to improve the steel’s oxidation resistance and formability.
In terms of mechanical properties, A283/A283M-13 steel grade has a minimum yield strength of 230 MPa and a minimum tensile strength of 415 MPa. It exhibits good weldability and formability, making it suitable for various fabrication processes. The steel grade also has excellent toughness and impact resistance at room temperature.
The A283/A283M-13 steel grade conforms to the ASTM A283/A283M standard, which specifies the general requirements for carbon steel plates of low and intermediate tensile strengths. This standard ensures consistent quality and performance of A283/A283M-13 steel grade in various applications.
Overall, the A283/A283M-13 steel grade offers a combination of strength, versatility, and cost-effectiveness, making it widely used in the construction industry for various structural applications.
