2.P460NH, so-called for having a minimum yield strength of 460 MPa, is a high-quality pressure vessel steel grade for use in boiler and pressure vessel fabrication. It is normalized 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 shallow 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
