FAQ:
Dab tsi yog qhov muaj pes tsawg leeg ntawm S890QL1?
S890QL1 yog quenched thiab tempered siab - lub zog hlau nrog ib tug raug muaj pes tsawg leeg ntawm cov pa roj carbon tsawg (tsawg dua los yog sib npaug rau 0.20%), manganese (Less tshaj los yog sib npaug rau 1.70%), thiab micro-alloying ntsiab xws li chromium, molybdenum, thiab npib tsib xee, xa ib tug tsawg kawg nkaus rau 4℃ntawm formulated toughness .
Puas yog S890QL1 thiab S890QLS Steel Phaj yog tib yam khoom?
S890QL1 thiab S890QL steel daim hlau tsis zoo ib yam, txawm hais tias lawv zoo sib xws heev - lub zog cov qauv hlau raws li EN 10025-6 tus qauv. Qhov sib txawv tseem ceeb yog lawv qhov kev xav tau ntawm qhov toughness: S890QL yuav tsum muaj kev cuam tshuam lub zog ntawm -40 degree, thaum S890QL1 yuav tsum muaj kev cuam tshuam hnyav -60 degree, ua QL1 haum rau cov ntawv txias dua.
Qhov sib npaug ntawm Lub Zog Muaj Zog Kub Rolled S890ql1 Steel Sheet rau Cov Qauv
"QL" nyob rau hauv S890QL siab steel qauv stands rau quenched thiab tempered cov txheej txheem thermal uas yog siv los txhim kho cov neeg kho tshuab yam ntxwv ntawm cov hlau.
