TS EN 10025-6 S890QL1 Steel Phaj

Jan 04, 2026 Tso lus

S890QL 1yog European-tus qauv, ultra- siab- lub zog, nplua -cov qauv hlau (EN 10025-6) uas tau quenched thiab tempered, muab qhov tsawg kawg nkaus tawm lub zog ntawm 890 MPa thiab zoo heev toughness, tshwj xeeb tshaj yog nyob rau hauv qis 6 lub tswv yim rau loads rau - avi. cov qauv xws li cranes, cov tshuab hnyav, thiab tsheb. Tus "S" txhais tau hais tias cov qauv, "890" yog lub zog tawm los, "Q" txhais tau tias quenching, thiab "L1" qhia txog qhov tshwj xeeb uas tsis tshua muaj kev cuam tshuam lub zog.

 

Cov yam ntxwv tseem ceeb:

Siab zog:Muab superior durability nrog qhov tsawg kawg nkaus yield zog ntawm 890 MPa.

Toughness:Nta muaj kev cuam tshuam zoo heev, txawm tias qhov kub thiab txias heev (xws li, 30 Joules ntawm -60 degree).

Weldability:Yuav tau welded zoo, txawm tias preheating tej zaum yuav xav tau rau cov seem tuab los yog txias txias los tiv thaiv cov kab nrib pleb.

Zoo-Ntaus:Txheej txheem kom muaj cov qauv zoo grain rau txhim kho toughness.

Dab tsi yog qhov txawv ntawm s890ql1 thiab s890ql?

nws qhov sib txawv tseem ceeb ntawm S890QL thiab S890QL1 yog qhov tshwj xeeb yam tsawg kawg nkaus ntawm lub zog xav tau ntawm qhov kub thiab txias: S890QL yuav tsum muaj kev cuam tshuam zoo ntawm -40℃, thaum S890QL1 muaj zog dua, lav qhov cuam tshuam tsawg kawg ntawm lub zog ntawm qhov txias txias ntawm -60 degree, ua rau nws zoo dua rau qhov txias txias. Ob leeg yog ultra{14}}lub zog siab, quenched thiab tempered structural steels (EN 10025-6) nrog qhov tsawg kawg nkaus tawm lub zog ntawm 890 MPa, tab sis lub npe 'L1' qhia txog kev ua tau zoo ntawm huab cua txias.
