EN10028 steel grade supersedes the older BS and DIN standards. P355GH steel grade is one of grade in En10028-2, which is non alloy and alloy steels with specified elevated temperature properties. P355GH grade are used above all for manufacturing boilers, pressure vessels and pipes transporting hot liquids.
