What is SA 283 C equivalent to?

 

ASME SA 283 GR C is a low-carbon steel plate with moderate tensile strength of 55-75 ksi (380-515 MPa), widely used for pressure vessels and structural applications due to its excellent weldability and formability. Its equivalents include ASTM A283 Grade C, EN 10025 S235JR, and IS 2062 E250, offering similar properties for general fabrication. As a leading Chinese manufacturer and exporter, Gangsteel produces high-quality sa 283 grade c steel plate under asme sa 283/sa 283m, ensuring compliance with ASME and equivalent standards for global projects.

 

Overview of SA 283 GR C and Its Equivalents

SA 283 GR C is part of the ASME SA 283 specification for low and intermediate tensile strength carbon steel plates, suitable for welded pressure vessels and structural components. Equivalents like ASTM A283 Grade C (identical in specs), EN 10025 S235JR (European structural steel), and IS 2062 E250 (Indian standard) provide comparable strength and weldability for similar uses.

Gangsteel's sa 283 grade c steel plate matches these equivalents, complementing grades like sa 283 grade a steel plate, sa 283 grade b steel plate, and sa 283 grade d steel plate for versatile applications.
