Chemical composition and tensile yield strength of S355G10+M offshore platform steel

Introduction of S355G10+M steel plate:
S355G10+M steel plate is structural steel for marine engineering, which belongs to European standard high-strength structural steel. S355G10+M offshore platform steel plate has good mechanical properties, welding properties and process properties. Commonly used in the manufacture of offshore oil drilling platforms, terminal equipment and other equipment. "S" indicates structural steel, "355" indicates low yield strength of steel plate, and "G10" indicates mechanical property test simulating post-weld heat treatment. "M" means controlled rolling. The same series of steel grades are: S355G5+M, S355G6+M, S355G7+M, S355G7+N, S355G8+M, S355G8+N, S355G9+M, S355G9+N, S355G10+N.
