ASTM A283 Steel, grade A Product Information -:- For detailed product information, please contact sales. -: ### **Technical Data Sheet: ASTM A283 / A283M Steel, Grade A** --- #### **1. Product Overview** ASTM A283 Grade A is a **low-carbon steel plate** designed for general structural applications where maximum strength is not the primary requirement. As the lowest strength grade in the A283 standard, it offers good formability, weldability, and cost-effectiveness for various structural purposes. This grade is commonly used in building construction, bridge components, and general fabrication where moderate strength and good ductility are sufficient for the application requirements. --- #### **2.
