2.P355NH, NL1 & NL2 – pressure vessel steels used by the worlds leading fabricators supplying the oil and gas industry. A pressure vessel steel grade with good weld ability and high resistance to brittle cracking, P355NH is used by the world's fabricators for the manufacture of pressure vessel tanks for the storage of pressurized gases.
3.Other grade types include...
NL1 – is ideal for use in low temperatures
NL2 – is ideal for use in especially low temperatures
P355NH is a normalized steel grade with a minimum yield strength of 275-460 N/mm² and plates are available ex–stock from our warehouse.
