ASTM A992 is a standard specification for structural steel shapes, plates, and bars used in building construction. It was developed by the American Society for Testing and Materials to ensure high-quality materials that provide strength and durability. This specification is commonly used for steel beams and columns in commercial and industrial buildings. The key features of ASTM A992 include its excellent weldability, high strength-to-weight ratio, and resistance to corrosion. It typically has a yield strength of 50 ksi (kilopounds per square inch) and is designed to meet the demands of modern construction practices, making it a preferred choice for engineers and architects.
