NFA 36201 E 460 FP steel 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.
NFA 36201 E 460 FP steel is also used in sour gas applications where the steel will be HIC Tested to gauge the materials susceptibility to hydrogen induced cracking.
