P420M and P420ML1 pressure vessel steel plate
Source:Yusheng steel
Pressure vessel steel plate P420M and steel sheet P420ML1 are both owned the minimum yield strength at 420 Mpa for the
plates thickness belows 16mm.When production these boiler steel plates P420ML1 and P420M,the heat treatment shall be
done under Thermomechanically rolled.Low temperature impacting test for steel grade P420M shall be done at minus 20
centi degree,and low temperature impacting test for steel grade P420ML1 shall be done under 40 centi degree.
Yusheng Iron and Steel Co.,Limited sucessfully exported thousands tons steel products of P420M and P420ML1 to
European countries.All the steel products have been approved by CE mark.Else,according to customers demands,we also
can accept the third party inspection in our mill or our stock warehouse or sea port,such as TUV,DNV,GL,LR and so on
for giving our vast customers’ satisfactory steel products.
