Typical Application : Critical Joints

S355G8+N /+M offer great tensile and yield strength, common structural grade steel frequently used by the offshore industry. Both can be delivered as S355G8+N (N= Normalized) and SG355G8+M (M= Thermo-Mechanically Rolled). As an offshore steel grade, S355G8+N and S355G8+M are used in a variety of applications including the building of offshore platforms.
