This specific type of steel, designated under ASTM A513, is a hot-rolled, carbon-manganese steel available in several grades (Type 1, Type 2, Type 5, Type 6, Type 7, and Type 10). Each grade offers a distinct balance of strength, ductility, and weldability, making them suitable for diverse applications. For instance, Type 1, a common choice, exhibits good formability and weldability ideal for general-purpose welded construction. Type 5 and Type 10 offer higher strength levels often required in more demanding situations.
The controlled chemical composition and manufacturing process of this material contribute to its consistent mechanical performance and reliable fatigue resistance. This predictable behavior is essential in applications where structural integrity is paramount, such as in automotive components, agricultural equipment, and construction machinery. Historically, its development addressed the need for a cost-effective, readily weldable steel with good mechanical properties, impacting industries reliant on high-strength, lightweight materials.
