ASME SA 283 GR C is a low-carbon steel plate specification under ASME SA 283/SA 283M, offering moderate tensile strength of 55-75 ksi (380-515 MPa) and excellent weldability for pressure vessels and structural applications.
It is part of a family of grades designed for low to intermediate strength requirements, with good formability and ductility. As a leading Chinese manufacturer and exporter, Gangsteel produces high-quality sa 283 grade c steel plate within our asme sa 283/sa 283m range, ensuring compliance with ASME standards for global fabrication projects.
SA 283 GR C is a carbon steel plate grade under ASME SA 283, suitable for welded pressure vessels, storage tanks, and general structural components where moderate strength is sufficient. It is not heat-treated, providing ease of fabrication but limited to low-pressure environments.
Gangsteel's sa 283 grade c steel plate is produced with controlled chemistry for enhanced performance, complementing other grades like sa 283 grade a steel plate, sa 283 grade b steel plate, and sa 283 grade d steel plate for versatile use in construction and engineering.

Gangsteel's asme sa 283/sa 283m plates meet these properties, with optional testing for specific applications.
SA 283 GR C is used in low-pressure tanks, structural beams, and general fabrication where moderate strength and good weldability are key. It is not suited for high-pressure or elevated-temperature service. Gangsteel's sa 283 grade c steel plate is popular for these uses, offering cost-effective solutions.
