Cov Lus Qhia Tseem Ceeb rau Kev Muag Khoom & Kev Sib Koom Tes
Thaum hloov S890Q nrog cov qhab nia sib npaug, ua tib zoo mloog cov ntsiab lus tseem ceeb no (qhov tseem ceeb rau kev zam cov khoom lag luam txaus ntshai):
ib. Core Performance Metrics los txheeb xyuas
Yield zog (YS): Xyuas kom cov qib sib npaug muaj qhov tsawg kawg nkaus YS ntawm 890 MPa (piv txwv li, ASTM A514 Gr. E thiab GB Q890GJ ua tau raws li qhov no; ASTM A709 Gr. 100 tsis - zam rau siab - lub zog xav tau).
Kev kho cua sov: S890Q yog xa hauvquenched thiab tempered (Q & T)mob. Cov qhab nia sib npaug yuav tsum yog Q&T (xws li JIS HSL890, GOST 09Г2СБФТ) - zam cov qib qub (N) lossis kub- dov (HR) qib.
Impact Toughness: S890Q yuav tsum muaj qhov cuam tshuam tsawg kawg nkaus ntawm 40 J ntawm -20℃(EN 10025-6). Txheeb xyuas cov qib sib npaug 'kev ntsuas qhov ntsuas kub (xws li ASTM A514 Gr. E siv -10℃lossis -20 degree; paub meej nrog cov neeg muag khoom).
Weldability: S890Q yog weldable nrog preheating kom zoo. Cov qib sib npaug (piv txwv li, GB Q890GJ, ASTM A514 Gr. E) muaj qhov zoo sib xws, tab sis lees paub cov tshuaj muaj pes tsawg leeg (xws li, carbon sib npaug CEV) rau siab - siv zog.
b. Daim ntawv thov -Kev hloov pauv tshwj xeeb
Heavy Machinery / Offshore: Ua ntej qhov sib npaug ncaj qha (ASTM A514 Gr. E, ISO S890Q) rau kev thauj khoom tseem ceeb-cov kabmob.
Kev tsim kho (Bridges/Buildings): GB Q890GJ lossis ASTM A709 Gr. 100 (yog tias muaj zog tso cai) yog nyiam rau kev ua raws cai hauv cheeb tsam.
Automotive: JIS HSL890 yog tsim rau kev lag luam Nyij Pooj, thaum ASTM A514 Gr. E ua haujlwm rau North American cov neeg siv khoom.

Q1: Puas yog S890Q sib npaug rau ASTM A36?
Tsis yog. ASTM A36 yog ib qho qis - carbon structural steel (min YS: 250 MPa) - deb zog qis dua S890Q (890 MPa). Lawv tsis yog interchangeable.
Q2: Kuv puas tuaj yeem hloov S890Q nrog Q690 steel?
Q690 (piv txwv li, EN 10025-6 S690Q) muaj min YS ntawm 690 MPa - 200 MPa qis dua S890Q. Tsuas yog hloov pauv yog tias daim ntawv thov lub zog yuav tsum tau hloov kho.
Q3: Qhov txawv ntawm S890Q thiab S890QL yog dab tsi?
"S890QL" yog lublow-kub toughness variantRaws li S890Q (EN 10025-6). Nws yuav tsum muaj kev cuam tshuam lub zog ntawm 40 J ntawm -40℃(vs . -20℃rau S890Q). Lawv tsis yog qhov sib npaug ncaj qha - QL qib yog rau qhov chaw txias (xws li, Arctic tej yaam num).
