2.P460NH, so called for having a minimum yield strength of 460 MPa, is 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.

3.Other grade types include...

NL1 – is ideal for use in low temperatures

NL2 – is ideal for use in especially low temperatures

P460NH is also used in sour gas applications where the steel will be HIC Tested to gauge the materials susceptibility to hydrogen induced cracking
