A283 Grade C is a widely recognized low carbon steel grade under the ASTM (American Society for Testing and Materials) standard, specifically designed for structural applications. A283 Grade C carbon steel offers a balanced combination of strength, ductility, and weldability. A283 Grade C low carbon steel provides excellent formability and cost-effectiveness, ideal for projects requiring moderate strength and durability.

A283 Grade C low-alloy carbon steel is particularly noted for its ability to withstand moderate stress while maintaining good weldability and machinability. Compared to higher grades like A283 Grade D, it has slightly lower tensile strength but excels in applications where weight reduction and ease of fabrication are priorities. Its performance in low-temperature environments also makes it suitable for specific industrial needs, A283 Grade C Low Carbon Steel is extensively used in the construction of buildings, bridges, and industrial equipment due to its reliable mechanical properties. It is commonly applied in manufacturing storage tanks, pressure vessels, and other structural components where moderate strength is sufficient.
