Normalized steel plate P460NH and P355NL2
Source:Yusheng steel
These two pressure vessel steel grades P460NH and P355NL2 both owned higher tensile and yield strength. Boiler steel
plates P460NH tensile strength is at 570_720 Mpa for thickness belows 60mm,even maximum 730 Mpa is OK for the product
thicknesses up to 16 millimeters.Pressure vessel steel plates P355NL2 tensile strength shall be within 490_630 Mpa for thickness
belows 60mm,and yield strength shall be above 355Mpa.
Steel sheet P355NL2 shall be done low temperature impacting test at minus 50 centi degree on transverse direction at minimum
27 J energy.Steel sheet P460NH shall be at minus 20 centi degree on transverse at minimum 30 J impacting energy.Now we list
the mechincal property table of steel P460NH as belows:
