EN10028-5 P355M,P355M Pressure Vessel Steel Plate
P355M is a thermo mechanically rolled and weldable fine grain steels grade.Pressure vessel steel plate P355M have to be under thermomechanically rolled when producing.As for the named of these steel plate P355M,P is short for steel for pressure vessels and boilers,the number 355 stand for the minimum yield point should be 355 Mpa for this steel,M is short for the heat treatment of thermomechanically rolling and do low temperature impacting test at minus 20 centi degree.
P355M pressure vessel steel is widely used in petroleum, chemical industry, power station, boiler, etc, used to make the reactor, heat exchanger, separator, liquefied gas, nuclear reactor pressure vessel, boiler steam drum steam, liquefied petroleum, hydropower station, high pressure pipe, spiral case and other equipment and components.
