S890 qwyog cov qauv steel qib nrog lub zog tawm los ntau dua li S690QL. Cov khoom siv ua ib qho kev xaiv zoo rau cov neeg muag khoom uas xav txhawb lub zog siab hauv kev siv nyiaj zoo. Vim yog cov yam ntxwv ntawm cov hlau, cov neeg siv khoom tuaj yeem siv cov khoom siv no hauv ntau daim ntawv thov uas ua rau muaj kev tsim kho kom zoo thaum tseem tuav lub zog zoo.
S890QL yog dej quenched & tempered steel uas ua raws li EN10025: 6: 2004 specification.
Thov xa mus rau cov lus qhia hauv qab no xa mus rau S890QL.

1.Dab tsi yog qhov txawv ntawm S890QLand S890Q?
Qhov sib txawv ntawm S890QL thiab S890Q yog qhov tsawg kawg nkaus cuam tshuam lub zog xav tau, nrogS890 qwqhia qhov tsawg kawg nkaus lub zog ntawm 30 Joules tsis qis dua-50 degree, hosS890QFeem ntau hais txog qib qis zog (piv txwv li, 30J ntawm -20℃) lossis tsis muaj qhov tshwj xeeb qis- qhov kub thiab txias yuav tsum tau ua, ua rau S890QL zoo dua rau cov ntawv siv txias dua vim nws qhov kev txhim kho toughness. Ob leeg yog high-yield zog structural steels (890 MPa) muab nyob rau hauv lub quenched thiab tempered mob (Q) raws li EN 10025-6.
2.Dab tsi yog S890QL cov khoom sib npaug?
S890QL yog ib qho ultra- lub zog muaj zog steel qauv (EN 10025-6) nrog 890 MPa yield zog, quenched & tempered; Qhov sib npaug tseem ceeb suav nrog ASTM A514 (zoo sib xws, cov khoom sib txawv), Strenx® 900 E, thiab cov npe lag luam xws li DILLIMAX 890T lossis WELDOX 900, nrog Q890 (Tuam Tshoj) thiab TStE 890 V kuj yog cov qib sib piv rau cov ntawv siv zoo sib xws.
