P460NH Pressura Vas Steel Plate

P460NH, sic dicta quod minimum cedat robur 460 MPa, est princeps qualitas pressionis vasis ferri gradus ad usum in boilo et pressione vasis fabricandi. Dilatatum est granum pulchrum ferro cum notis beneplacitis.

Aliae rationes gradus includunt…
NL1 - est specimen pro usu in low temperaturis
NL2 - est specimen pro usu maxime humilis temperaturis

P460NH adhibetur etiam in applicationibus gasis acerbis, ubi ferrum HIC Expertum erit ad coniecturam materiae susceptibilitatem ad hydrogenii crepturam inducendam.
