P355QL1 and P355QL2 Pressure vessel steel plate
Source:Yusheng steel
With the minimum yield strength at 355 Mpa,steel plates and sheets P355QL1 and P355QL2 are mainly used for pressure
vessels,liquid boilers and tanks.All these pressure vessel steel plate P355QL1 and P355QL2 have to be done heat treated
under Quenched and Tempered when rolling.As for the low temperature impacting test,steel plate and sheet P355QL1 s
hall be done at minus 40 centi degree and steel plate and sheet P355QL2 shall be done at minus 50 centi degree.
As for the chemical composition for these steel grades P355QL1 and P355QL2,now YUSHENG STEEL list the chemical
table for your check,our rolling would be completely according to this limited and range.Elements not listed in this tabe
shall not be intentionally added to the steel without the agreement in buyer’s purchaser order except for finishing the steel
cast.All appropriate measures shall be taken to prevent the addition from scrap and other materials used in steelmaking of
these elements.
