HIC/NACE Steel Plate Grade

What is A283 Grade C equivalent to?

 

ASTM A283 Grade C is a low-carbon steel plate with moderate tensile strength of 55-75 ksi (380-515 MPa), commonly used for structural applications and pressure vessels due to its good weldability and formability.

Its equivalents include EN 10025-2 S235JR (European), IS 2062 Grade E250A (Indian), and GB/T 700 Q235C (Chinese), all offering similar low-strength 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 ASTM and equivalent standards for global projects.

 

Overview of A283 Grade C and Its Equivalents

 

ASTM A283 Grade C is a low and intermediate tensile strength carbon steel plate used in structural applications like buildings, bridges, and tanks, where moderate strength and good formability are essential.

Equivalents like EN 10025-2 S235JR and IS 2062 Grade E250A provide comparable yield and tensile strengths for similar uses in Europe and India. Gangsteel's sa 283 grade c steel plate matches these equivalents, 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 structural applications.
