ASME SA 283 Grade 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 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.
ASME SA 283 Grade C specifies carbon steel plates for moderate and lower temperature pressure vessels and general structural uses, with a focus on weldability and moderate corrosion resistance. It is supplied in as-rolled condition, with thicknesses typically up to 2 inches for optimal performance. Gangsteel's sa 283 grade c steel plate meets these specs, 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 applications.
