P460N/P460NH steel , P460N/P460NH steel supplier

Pressure vessel steel plate P460N and P460NH under European standard EN10028_3 shall be made of steels for pressure purposes . P460N steel plate is under the room temperature quality,and P460NH is under the elevated temperature quality . Comparison with other lower yield strength in tradehis standard,such as P355N and P355NH,these two steel grade have more alloy elements , such as Cu,Cr,V.More carbon contains improved its tensile strength in steel properity.

P460NH steel , so called for having a minimum yield strength of 460 MPa, it is a high quality pressure vessel steel grade for use in boiler and pressure vessel fabrication. It is a normalised fine grain steel with good weldability characteristics.

Other grade types include...

P460NL1 – is ideal for use in low temperatures
P460NL2 – is ideal for use in especially low temperatures
