ASME SA283 Grade D Specifications

ASME SA283 Gr 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) and good weldability 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.

Overview of ASME SA283 Gr D Specifications

ASME SA283 Gr D specifies carbon steel plates for moderate and lower temperature pressure vessels and structural components, with a focus on higher strength than lower grades. It is supplied in as-rolled condition, with thicknesses typically up to 2 inches for optimal performance. Gangsteel's sa 283 grade d steel plate meets these specs, 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 applications.

The table below summarizes key specifications for SA283 Gr D:

Chemical Composition of ASME SA283 Gr D

The chemical composition is limited to ensure low carbon for better weldability and formability. Below is a table of the specified composition (in weight %, maximum unless range):

Gangsteel's sa 283 grade d steel plate adheres to these limits for consistent quality.

Mechanical Properties of ASME SA283 Gr D

SA 283 Gr D offers intermediate mechanical properties, with no special heat treatment required. The table below details the requirements:

Gangsteel's asme sa 283/sa 283m plates meet these properties, with optional testing for specific applications.

Applications of ASME SA283 Gr D

ASME SA283 Gr D is applied in higher-strength pressure vessels, structural beams, and general fabrication where greater tensile strength than Grade C is required. It is not recommended for high-pressure or elevated-temperature service. Gangsteel's sa 283 grade d steel plate excels in these applications, offering cost-effective solutions.
