Qhov sib txawv ntawm P460QL1 thiab P690QL1 steel phaj

Jan 21, 2026 Tso lus

P460QL1 thiab P690QL1 yog siab- lub zog, nplua- cov qib steel qib los ntawm EN 10028-6 tus qauv, tsim rau cov hlab ntsha siab thiab siab - cov khoom siv kub, qhov sib txawv ntawm lub zog: P460QL1 muaj qhov tsawg kawg nkaus ntawm Q6 y Q6 siab dua 690 MPa, ob qho tib si cua sov- kho (Quenched thiab Tempered - 'QL') rau qhov kub thiab txias toughness (-40℃).

Cov yam ntxwv tseem ceeb & qhov sib txawv

Txheem: Ob qho tib si poob rau hauv EN 10028-6, qhia meej weldable steels rau lub hom phiaj siab.

Kev kho cua sov: 'Q' txhais tau tias Quenched, 'L' txhais tau tias Tsawg-kub toughness (tshwj xeeb -40℃cuam tshuam kev xeem), thiab '1' qhia txog kev cuam tshuam lub zog (xws li, 27J).

Lub zog: Tus lej qhia qhov tsawg kawg nkaus lub zog: P460QL1 (460 MPa) vs. P690QL1 (690 MPa).

Daim ntawv thov: Siv nyob rau hauv xav tau siab - kub, siab - qhov chaw siab xws li boilers thiab siab hlab ntsha, qhov twg zoo weldability tseem ceeb heev.
