Qhov sib txawv tseem ceeb yog tias P460Q yog qhov dav dav dav - lub zog zoo- cov hlau, thaum P460QH (thiab P460QL1/2) txhais tau tiastshwj xeebqis- qhov yuav tsum tau muaj qhov kub thiab txias (xws li, -20℃rau Q, -40℃rau QL1, -60℃rau QL2) nrog cov kev ntsuas cuam tshuam lub zog (xws li 27J), ua rau P460QH zoo dua rau cov hlab ntsha cryogenic lossis txias-kev pabcuam, ob qho tib si ntsib EN 10028-6 cov qauv siab thiab boilers.
Ntawm no yog ib qho kev piav qhia ntawm cov npe:
P (Plate): Qhia tias nws yog cov khoom siv phaj.
460 (Yield Strength): Qhia qhov tsawg kawg nkaus lub zog ntawm 460 MPa.
Q (Quenched & Tempered): txhais tau tias cov hlau yog cua sov-kho (quenched thiab tempered) kom zoo zog thiab toughness.
H / L1 / L2 (Toughness Level): Cov lus kawg no qhia txog Charpy cuam tshuam qhov ntsuas kub:
P460Q: Basic -20℃cuam tshuam kuaj.
P460QH: Zoo dua rau qhov kub thiab txias, feem ntau -20℃nrog 27J cuam tshuam.

Hauv cov ntsiab lus: Ob leeg muaj zog, weldable steels rau boilers / siab hlab ntsha, tab sis "H" (los yog "L1", "L2") nyob rau hauv P460QH ntxiv ib qho tseem ceeb yuav tsum tau rau guaranteed kev ua tau zoo ntawm qhov kub thiab txias, ua rau nws tshwj xeeb tshaj yog rau txias- kev pab cuam daim ntaub ntawv tshaj lub hauv paus P460Q.
