SA 283 Gr C chemical composition

SA 283 Gr C Chemical Composition

ASME SA 283 GR C is a low-carbon steel plate with a maximum carbon content of 0.24%, designed for moderate tensile strength and excellent weldability in pressure vessels and structural applications. Its chemical composition is controlled to minimize impurities, ensuring good formability and resistance to brittleness. 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, adhering to ASME standards for global fabrication projects.

 

What is SA 283 GR C Chemical Composition?

The chemical composition of SA 283 GR C emphasizes low carbon for enhanced weldability and ductility, making it suitable for general structural uses. It includes limits on manganese, phosphorus, and sulfur to prevent defects like cracking during processing.

Gangsteel's sa 283 grade c steel plate is manufactured with precise composition control, 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.

Mechanical Properties Influenced by Composition

The low-carbon composition of SA 283 GR C contributes to its mechanical properties, including a minimum yield strength of 30 ksi (205 MPa) and tensile strength of 55-75 ksi (380-515 MPa). This ensures good ductility without excessive hardness. Gangsteel's asme sa 283/sa 283m plates maintain these through quality production.

 

Applications of SA 283 GR C Material

With its balanced composition, SA 283 GR C is used in low-pressure tanks, structural beams, and general fabrication where weldability is key. It is not suited for high-pressure service. Gangsteel's sa 283 grade c steel plate excels in these applications, offering cost-effective solutions.
