A653/A653M-17 is a standard specification for steel sheet, zinc-coated (galvanized) or zinc-iron alloy-coated (galvannealed) by the hot-dip process. It covers the requirements for the commercial steel grades (CS types A, B, C) and structural steel grades (SS grades 33, 37, 40, 50, 55, 80) of zinc-coated galvanized or galvannealed steel sheets.
The chemical composition of A653/A653M-17 steel grade includes carbon (C), manganese (Mn), phosphorus (P), sulfur (S), and other elements such as aluminum (Al), silicon (Si), and trace amounts of various elements. The specific chemical composition may vary depending on the steel grade and the manufacturing process.
The mechanical properties of A653/A653M-17 steel grade are specified through various tests including tensile strength, yield strength, elongation, and bendability. These properties are important for determining the strength, ductility, and overall performance of the steel in different applications.
The properties of A653/A653M-17 steel grade make it suitable for various applications in industries such as construction, automotive, appliances, and manufacturing. It is commonly used in the fabrication of roofing, siding, ductwork, and other structural components where corrosion resistance and durability are essential.
The A653/A653M-17 steel grade is identified by its standard number, which refers to the specific edition of the ASTM A653/A653M standard that the product conforms to. This standard provides a set of requirements and test methods for the zinc-coated galvanized or galvannealed steel sheets, ensuring quality and consistency in the manufacturing process.
In summary, understanding the chemical composition, mechanical properties, and standard number of A653/A653M-17 steel grade is important for choosing the right material for specific applications. This steel grade offers good corrosion resistance, durability, and strength, making it suitable for a wide range of industrial and commercial applications.
