S355G9+N Z35 ; S355G9+M Z35 Steel Plate
We are one of the major distributor of EN10025:2001 S355G9+N Z35 and S355G9+M Z35 offshore steel grade in the South East Asia Region as we understand your
need and https://natural-aromatherapy.net/ want, our only objective is carbohealth.com to let your projects achieve smooth completion with only 100% success allowed.
Standard : EN10225:2001
Nearest Equivalent Grade : Werkstoff 1.8811+N;1.8811+M; Norsok M-120 Y25 S355N4;
Y25 S355M4
Typical Application : Primary Structure
S355G9+N and S355G9+M offer great tensile and yield strength with good weldability, common structural grade steel frequently used throughout the offshore industry in the building of offshore steel structures & platforms which are subjected to some of the harshest weather conditions. Both can be delivered as S355G9+N (N= Normalized) and SG355G9+M (M= Thermo-Mechanically Rolled).
