S355G9+M S355G10+M HSLA steel plate
S355G9+M low alloy steel plate is a hot rolled steel plate for structural use with high strength and good weldability. The material complies with EN 10225 and is suitable for offshore structures and marine engineering. The S355 indicates that the steel has a minimum yield strength of 355 MPa, the G9 indicates a maximum thickness of 9 mm where variability needs to be controlled, and the M indicates weldability. Overall, S355G9+M is a high-strength steel plate for offshore structures.
S355G10+M steel plate is a structural steel for offshore engineering, which belongs to the European standard high strength structural steel.S355G10+M steel plate has good mechanical properties, welding properties, and process properties. S355G10+M steel plate has good mechanical properties, welding properties, and process properties. "S" means structural steel, "355" means low yield strength of steel plate, "G10" means simulation of post-weld heat treatment mechanical properties test. "M" indicates controlled rolling.
