ASME SA 283 Grade D is a low-carbon steel plate specification under ASME SA 283/SA 283M, offering higher tensile strength of 60-80 ksi (415-550 MPa) compared to lower grades, with good weldability and formability for pressure vessels and structural applications. It is designed for intermediate strength requirements, suitable for environments where moderate corrosion resistance and ductility are needed. As a leading Chinese manufacturer and exporter, Gangsteel produces high-quality sa 283 grade d steel plate within our asme sa 283/sa 283m range, ensuring compliance with ASME standards for global fabrication projects.
SA 283 Grade D is a carbon steel plate grade under ASME SA 283, used for welded pressure vessels, storage tanks, and structural components where higher strength than Grade C is required. It is supplied in as-rolled condition, providing ease of fabrication but limited to low-pressure environments.
Gangsteel's sa 283 grade d steel plate offers balanced properties, complementing lower grades like sa 283 grade a steel plate, sa 283 grade b steel plate, and sa 283 grade c 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 Grade D is used in higher-strength pressure vessels, structural beams, and general fabrication where greater tensile strength than Grade C is needed. It is not suited for high-pressure or elevated-temperature service. Gangsteel's sa 283 grade d steel plate excels in these applications, offering cost-effective solutions.
