ASTM A1003/A1003M-15 is a standard specification for steel sheet, carbon, metallic and nonmetallic-coated for cold-formed framing members. It provides the chemical composition and mechanical properties required for this type of steel grade.
The chemical composition of ASTM A1003/A1003M-15 steel grade includes elements such as carbon, manganese, phosphorus, sulfur, aluminum, and silicon. The maximum content of carbon is 0.10%, manganese is 1.60%, phosphorus is 0.035%, sulfur is 0.020%, aluminum is 0.10%, and silicon is 0.60%.
The mechanical properties of ASTM A1003/A1003M-15 steel grade are specified in terms of yield strength, tensile strength, and elongation. The minimum yield strength is 33 ksi (230 MPa), minimum tensile strength is 45 ksi (310 MPa), and minimum elongation is 20%.
This steel grade is commonly used for cold-formed framing members in construction applications. It is suitable for use in load-bearing walls, floor systems, roof systems, and other structural elements. The high strength and rigidity of ASTM A1003/A1003M-15 steel grade make it ideal for supporting heavy loads and providing structural stability.
In addition to its structural applications, ASTM A1003/A1003M-15 steel grade can also be used for other purposes such as manufacturing roll-formed steel components, metal buildings, and other steel products.
Overall, ASTM A1003/A1003M-15 steel grade has a well-defined chemical composition and mechanical properties that make it suitable for various construction and manufacturing applications. Its strength, durability, and versatility make it a preferred choice for cold-formed framing members and other structural components.
