Accreditation Administration System:
Pressure vessel using steel plate P275NL1 and P275NL2 under the specifications EN 10028_3,which have
to done Normalised heat treatment when rolling.These two steel grades P275NL1 and P275NL2 are both
carbon manganese structural steels due to their high resistance to pressure at low temperature.Steel plate
P275NL1 must be done low temperature impacting test at minus 40 centi degree with minimum 27J on
transverse direction.Steel plate P275NL2 must be done impacting test at minus 50 centi degree.
Additional terms for P275NL1 and P275NL2 steel plate,if indicated by the manufacturer in order terms,
normalised may be replaced with normalised rolling on the basic of all the steel property is guarantee.
PWHT_Simulated post welded heat treatment can be chosed by end users,ao that improve the weldability
of this steel.
