P500QL1 STEEL PLATE

High strength P500QL1,P500QL1 steel plate,P500QL1 steel sheet,also named as boiler steel plate P500QL1,P500QL1 pressure vessel steel plate.because these steel plates are mianly used to built high temperature steel boilers and other pressure vessels.When rolling pressure vessel steel plate P500QL1,the low temperature impacting test shall be done at minus 40 centigree,Ultrasonis examination,heat treatment under quenched and tempered.Xinsteel exported thousands tons pressure vessels each month all over the world,especailly to southeast asia,middile east and South america.
