P355GH,P 355 GH,EN10028-2 P355GH STEEL PLATE

P355GH,P 355 GH,EN10028-2 P355GH STEEL PLATE
 
Unitedsteel mill is specialized in production super thickness steel plates. EN10028 steel grade supersedes the older BS and DIN standards (Grades BS 1501-161-360A and DIN H 1, respectively).
P355GH steel grade is one of grade in En10028-2, which is non alloy and alloy steels with specified elevated temperature properties. P355GH grades are used above all for manufacturing boilers, pressure vessels and pipes transporting hot liquids.
