EN 10025 2 S235JR steel equivalent ASTM A283 grade C

EN 10025 2 S235JR Steel Equivalent ASTM A283 Grade C

EN 10025-2 S235JR is a European standard non-alloy structural steel grade with a minimum yield strength of 235 MPa, known for its good weldability, machinability, and suitability for general construction. Its equivalent in ASTM standards is A283 Grade C, a low-carbon steel plate with similar moderate strength and properties for structural and pressure vessel applications.

As a leading Chinese manufacturer and exporter, Gangsteel produces high-quality plates equivalent to S235JR under asme sa 283/sa 283m, offering reliable alternatives for global projects in buildings, bridges, and machinery.

 

Overview of EN 10025-2 S235JR and ASTM A283 Grade C

EN 10025-2 S235JR is a hot-rolled structural steel used in non-critical applications like buildings and bridges, with good impact resistance at room temperature (JR designation). ASTM A283 Grade C is a low and intermediate tensile strength carbon steel plate for similar structural purposes, often used in tanks and general fabrication. Both have low carbon content for excellent weldability, making them interchangeable in many cases. Gangsteel's asme sa 283/sa 283m plates provide equivalent performance, including grades like sa 283 grade a steel plate, sa 283 grade b steel plate, sa 283 grade c steel plate, and sa 283 grade d steel plate for versatile structural needs.
