S275JR Carbon Steel Plate — Factory Direct Supplier | Huaxia-Steel

S275JR carbon steel plate is a low-carbon structural grade to EN 10025-2 with a minimum yield strength of 275 MPa and guaranteed impact toughness at +20 °C. It is widely used in construction, bridges, machinery and general engineering where moderate strength and excellent weldability are more important than the highest tensile values. Huaxia-Steel stocks and produces S275JR plate in commercial and precision tolerances with full certification.

Product Overview

Our S275JR plates are supplied as-rolled or normalized from killed steel. The lower carbon content compared with S355JR gives excellent weldability and formability, reducing preheat requirements and distortion during fabrication.
