EN 10216-4 P255QL seamless kavmuab los ntawm GNEE feem ntau yog siv rau hauv cov kev pabcuam nrog qhov kub thiab txias qis li -46 degree . P255QL, steel tooj 1.0452, yog ib qho ntawm cov hlau tsis muaj hlau zoo uas tau teev tseg hauv EN 10216-4. Rau cov ntawv thov cryogenic, EN 10216-4 P255QL yuav tsum tau ua kom tsis muaj menyuam. Tsab ntawv loj "P" sawv cev rau lub hom phiaj siab; "255" sawv cev rau qhov tsawg kawg nkaus tawm lub zog ntawm 255MPa; "Q" sawv cev rau kev kho cua sov rau quenching thiab tempering; "L" sawv cev rau lub hom phiaj kub qis.
Nquag, P255QL qib seamless kav lossis kav dej yuav tsum tau quenched thiab tempered. quenching kub (quenching kub) yog 890 degree rau 930 degree, thiab tempering kub yog 600 degree mus rau 680 degree.
