P275N STEEL PLATE

EN 10028-3 P275N,P257N steel plate,P275N steel sheet is the room temperature quality,P275NH steel plate 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.Normalised heat treatment and Ultrasonic test are both necessary for this steel grade P275N for guarantee its steel property.XINSTEEL owned the stock of P275N pressure vessel steel plates at our port warehouses for ready shipment with kinds of specifications.
