Under the standard EN10028_3,steel plate P275NH and P275N shall be both under Normalized delivery
condition when processing.These steel grade P275NH and P275N mainly used in pressure vessels and
boilers differ from other carbon_manganese structural steel plates owning to its high resistance to pressure
at all temperatures when usage.
Besides the Normalized,impacting test shall be done when rolling at minus 20 centi degree temperature
with minimum 30J energy on transverse direction,and with minimum 45J energy on longitudinal direction.
About our rolling thickness range for steel P275N and P275NH is 8mm_350mm,and guarantee the steel
property when delivery.Each plate shall be issued one Mill test certificate and indicate the values for
chemical composition and mechanical property.Now we give you our rolling specificaitons of Chemical
analysis for steel plate P275NH as belows:
