EN 10028 P355GH pressure-vessel steels Related grade

Posted:8/1/2016 2:32:29 AM

 

 

Widely used throughout the petrochemical industry, P355GH is a pressure vessel steel grade as specified under the Euro Norm standard (EN10028) which has superseded British Standard and DIN standard equivalents.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.
