P460NL2 STEEL PLATE

Low temperature impacting test for boiler P460NL2,P460NL2 steel plate,P460NL2 steel sheet shall be under minus 50 centi degree when rolling.For these pressure vessel steel plate P460NL2,additional technical needs,such as HIC and UT is normally chosed to do by end users when enquiry and making orders.HIC test shall be done in accordance with EN 10229 specification. Carbon and low alloy steels may be susceptible to cracking when exposed to corrosive H2S containing environments, usually referred to as sour service.With the minimum yield strength 355 Mpa,steel plate p460nl2 are mainly used for hot liquid pressure vessls and boilers in heavy industries.
