P355GH steel Widely used throughout the petrochemical industry, P355GH steel is a pressure vessel steel grade as specified under the Euro Norm standard (EN10028) which has superseded British Standard and DIN standard equivalents.
This normalized steel is used worldwide by fabricators of welded pressure vessels, industrial boilers and heat exchangers and is engineered to work well in elevated temperature service.
We offer grade EN 10028 P355GH from stock and the material is available for shipping to you worldwide. As with all of our steels, the material comes with mill test certification and stamping and is therefore fully traceable. We can also subject the material to a variety of stringent tests prior to distribution.
