P275N Steel Plate P275N Hot Rolled Steel Sheet P275N Carbon Steel Plates
EN 10028-3 P275N pressure vessel steel plate is the room temperature quality,P275NH is for the elevated temperature quality,P275NL1 is for the low temperature quality and P275NL2 is for the special low temperature quality.Generally,our engineers suggest that P275N boiler steel plates shall be done low temperature impacting test under minus 20 centigree.
