P460NL1 yog V thiab N txhawb nqa lub nkoj siab steel ua raws li European cov qauv, feem ntau yog tsim los siv rau hauv kev tsim cov roj thiab roj tanker tsheb, thiab tseem siv dav hauv Suav teb.
P460NL1 steel phaj yog qhov tsawg kawg nkaus lub zog ntawm 460MPa nplua nplej rau vuam ntawm cov hlau tsis tshua muaj siab-lub zog pob tank steel, P sawv cev rau lub siab, 460 sawv cev rau qhov tsawg kawg nkaus yield zog.
P stands rau siab, 460 stands rau yam tsawg kawg nkaus yield zog, N qhia tau hais tias tus me nyuam lub xeev ntawm cov hlau phaj yog normalised, thiab L1 qhia qhov tsis tshua muaj kub toughness series. Tuam Tshoj tam sim no.
P460NL1 mechanical zog:
Thickness Tsawg dua los yog sib npaug rau 16 Tawm lub zog Ntau dua lossis sib npaug rau 460, tensile zog 570-720.
Thickness 16-40 Yield zog Ntau dua los yog sib npaug rau 445, tensile zog 570-720.
Thickness 40-60 yield zog Ntau dua los yog sib npaug rau 430, tensile zog 570-720.
Thickness 60-100 yield zog Ntau dua los yog sib npaug rau 400, tensile zog 570-710.
P460NL1 yog siv rau hauv kev tsim cov khoom siv thiab cov khoom siv rau kev tsim cov reactors, kub exchangers, separators, pob tso tsheb hlau luam, roj thiab roj tso tsheb hlau luam, liquefied roj tso tsheb hlau luam, boiler ladles, liquefied petroleum cylinders, high-pressure dej kav rau hydroelectric power stations, turbine worm shells.
