S355N steel is a kind of normalized or normalized rolled weldable fine grain structural steels. The delivery condition for S355N must be Normalized heat treatment or Normalized rolled way. S355N steel grade material No. Is 1.0490
EN 10025 S355N steel have the good weldable and fine grain structural property. So, it can be used into the steel structural or welded vessel or pressure vessels.
Standard : EN 10025-3
Dimension range : 2-400mm * 1000-3800mm * 3000-18000mm
