Tus nqi ntawm S890QL steel phaj yog qhov sib txawv heev thiab kim kim dua li cov qauv hlau lossis txawm tias qis dua qib siab zog xws li S690QL. Tsis muaj tus nqi lag luam ruaj khov, vim nws nyob ntawm ntau yam. Txawm li cas los xij, cov hauv qab no muab lub hauv paus muaj tseeb rau kev kwv yees:
Tus nqi tseem ceeb tsav tsheb:
Order Specifications:
Thickness: Nqe nce sharply nrog thickness. Cov phaj siab tshaj 50 hli tuaj yeem raug nqi 50-100% ntau dua ib tuj dua cov phaj hauv qab 20 hli.
Dimensions & Quantity: Cov khoom me me, txiav-rau-loj nqa tau tus nqi loj. Kev txiav txim tag nrho zeb lossis cov khoom thauj khoom thauj (piv txwv li, 20+ tons) tau txais cov luv nqi tseem ceeb.
Certification & Testing:Standard EN 10204 3.1 ntawv pov thawj suav nrog. Cov kev xav tau ntxiv (piv txwv li, kev tshuaj xyuas thib peb, ncua kev sim ntawm -60 degree, lossis kuaj ultrasonic) ntxiv tus nqi.
Market & Supply Factors:
Raw Khoom Nqis: Alloying ntsiab (Ni, Cr, Mo, V) thiab lub zog-intensive quenching / tempering ua rau cov nqi rhiab rau cov khoom muag thiab lub zog ua lag luam.
Cov neeg tsim khoom lag luam txwv: S890QL yog tsim los ntawm qee qhov tshwj xeeb mills (piv txwv li, Dillinger, SSAB, voestalpine), yog li kev muaj nyob hauv cheeb tsam thiab kev sib tw cuam tshuam rau tus nqi.
Kev Ua Haujlwm & Logistics:
Kev Ua Haujlwm: Txiav, drilling, ntug kev npaj, lossis kev kho cua sov ntxiv tus nqi.
Kev xa khoom: Qhov chaw, txoj kev xa khoom, thiab Incoterms (xws li, EXW, FOB, xa) yog qhov tseem ceeb ntawm tus nqi kawg.
Tus nqi kwv yees (Cov lus qhia nkaus xwb):
S890QL feem ntau raug nqi 50-150% ntau dua S690QL vim nws txoj kev alloying ntau dua thiab ua tiav.
Tus nqi qis ib Metric Ton: Kwv yees li € 2,500 - € 5, 000+ (los yog sib npaug hauv USD / GBP).
Lower end: Large‑volume orders (>20 t) ntawm standard-loj, nruab nrab-thickness (20-40 mm) daim hlau.
Upper kawg: Tsawg-volume xaj (<5 t), very thick plates (>80 mm), cov ntawv txiav me me, lossis daim hlau nrog cov ntawv pov thawj tshwj xeeb / kuaj.
Yuav Ua Li Cas Tau Txais Qhov Tseeb Quote:
Txhawm rau kom tau txais cov lus hais muaj txiaj ntsig, muab cov neeg xa khoom nrog cov ncauj lus kom ntxaws Thov rau Quotation (RFQ) suav nrog:
