P460NH steel exporter, P460NH steel plate, P460NH steel Chemical Composition

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.

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

P460NH steel plate demension( T* W* L) : 6-250mm * 1500-4020mm * 3000-18000mm.
