P460QL2 and P460QL1 pressure vessel steel plate

Source:Source: Yusheng

 

Quenched and Tempered weldable fine grain steel plate P460QL2 and P460QL1 is mainly used to manufacture pressure vessels and boilers in recent heavy industy allover the world.Pressure vessel steel plate and sheet P460QL2 need to be done low temperature at minus 60 centi degree with the impacting energy above 27 J which is valid for transverse test pieces,and pressure vessel steel plate P460QL1 need to be done this test at minus 40 .

 

For these European specification steel grades P460QL1 and P460QL2,before shipment we can accept the relative third party inspection which our customers specified when making purchase orders.The main third inspection agency shall be TUV,DNV,LR,SGS and others.After done inspection,these third party inspection agency would stamped and endorsed on our Mill test certificates and their inspection report.We would submit these documents to our end users together with steel plates.
