201 J4 stainless hlau coils thiab nplooj ntawv
Tso lus
201 J4 stainless hlau kauj yog kev lag luam 200-series austenitic stainless hlau khoom, sub- qib ntawm 201 stainless hlau. Nws siv high-manganese nitrogen alloying los hloov qee cov npib tsib xee, ntsuas tus nqi zoo nrog cov qauv zoo thiab corrosion kuj. Nws yog dav siv hauv tsev kho kom zoo nkauj, chav ua noj, thiab kev lag luam teeb pom kev zoo.
201 J4 stainless hlau txias- dov kauj muaj 15.5-16.5% chromium (Cr), 1.2-1.8% nickel (Ni), 5.5-7.0% manganese (Mn), thiab 0.18-0.25% nitrogen (N). Cov ntsiab lus npib tsib xee yog siab dua 201 J1 / J2 / J5, thiab nws lub zog thiab corrosion kuj zoo dua li cov tsis tshua muaj npib tsib xee 201. Txawm hais tias qis dua 304 stainless hlau, nws yog txaus los tiv thaiv ib puag ncig atmospheric thiab tsis muaj zog corrosive ib puag ncig. Nyob rau hauv cov nqe lus ntawm txhua yam khoom: tensile zog Ntau tshaj los yog sib npaug rau 550MPa, yield zog Ntau tshaj los yog sib npaug rau 280MPa, elongation Ntau tshaj los yog sib npaug rau 40%. Nws muaj zoo heev txias dabtsi yog khoov thiab stamping formability, haum rau ua complex duab.
Peb muab 201 J4 txias- dov coils nrog tus qauv tuab ntawm 0.3-3.0mm thiab qhov siab tshaj plaws ntawm 1250mm. Kub-rolled coils muaj li ntawm 4-12mm nyob rau hauv thickness. Cov txheej txheem saum npoo yog 2B txias- dov thiab No.1 kub dov, thiab cov kev xaiv tom qab ua tiav suav nrog txhuam thiab iav tiav.

Dab tsi yog qhov txawv ntawm 201 J4 thiab 201 J5 stainless hlau coils?
J4 muaj cov ntsiab lus npib tsib xee ntau dua, ua rau muaj kev xeb zoo dua li qis -nickel variants xws li 201 J5. Nws yog 20-30% pheej yig dua 304 stainless hlau, muab tus nqi zoo heev. Txawm li cas los xij, nws tsis haum rau lub sijhawm ntev - raug rau qhov chaw ntub dej, muaj cov tshuaj chlorine siab (xws li cov chaw nyob sab nraum ntug dej hiav txwv) lossis thaj chaw acidic. Rau cov xwm txheej zoo li no, kev hloov kho rau 304 stainless hlau yog pom zoo.
201 J4 Stainless Hlau Coils Nqe
Tus nqi ntawm 201 J4 stainless hlau coils feem ntau yog li ntawm $ 850 mus rau $ 1,350 ib metric ton, nyob ntawm seb yam xws li thickness, nto tiav, thiab txiav txim kom muaj nuj nqis. Txij li Qib J4 stainless hlau nta cov ntsiab lus tooj liab ntau dua thiab cov ntsiab lus qis dua piv rau qib J1, J2, thiab J3, nws cov nqi muag feem ntau yog siab dua me ntsis.
Yog tias koj xav tau cov lus qhia meej rau qhov ntev, peb pom zoo kom muab cov tuab tuab, qhov ntev, thiab qhov dav uas koj xav tau, nrog rau seb puas yuav tsum tau txiav. Koj puas xav kom kuv xam qhov kwv yees qhov hnyav thiab tus nqi rau ib daim ntawv ntawm ib qho me me?
Material Test Certificate (MTC):
Txhua kauj yog nrog los ntawm cov ntaub ntawv qhia ntxaws qhia txog nws cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab.
Thib peb- Kev Tshawb Fawb Txog Kev Tshawb Fawb: Peb tuav ntev - kev koom tes nrog cov koom haum xws li SGS, BV, thiab TUV, ua rau peb tuaj yeem pab peb thib peb - kev tshuaj xyuas nrog rau kev tshuaj ntsuam xyuas tshuaj thiab qhov chaw tuab - tshuaj xyuas sawv cev ntawm peb cov neeg siv khoom ua ntej xa khoom.
Professional Ntim:
Peb muab cov kev xaiv ntawm ib los yog ob npaug - txheej 7C / 10C tiv thaiv zaj duab xis los xyuas kom meej tias qhov chaw ntawm peb cov khaub thuas txias - dov coils tseem tsis muaj khawb thoob plaws hauv kev thauj mus los thiab stamping txheej txheem. Tsis tas li ntawd, peb siv cov khoom ntim khoom muaj zog ntxiv- muaj cov ntawv tuab tuab, cov hlua khi steel, thiab cov ntoo pallet ruaj khov, tiv thaiv cov dej nkag hauv hiav txwv thaum thauj khoom hauv hiav txwv, yog li tshem tawm qhov kev pheej hmoo ntawm "sov xeb" (flash rust) ntawm 201 stainless hlau.
