Tso lus
Hauv kev lag luam thoob ntiaj teb stainless hlau, 201-series txias- dov stainless hlau coils tau tshwm sim los ua ib qho ntawm cov khoom siv tau zoo tshaj plaws rau kev kho vaj tse, kev tsim khoom siv hauv tsev, thiab kev siv lub teeb.
Txawm li cas los xij, ntau tus neeg yuav khoom tseem tawm tsam kom nkag siab qhov sib txawv tseem ceeb ntawm ntau qib - xws liJ1, J2, J3, J4, thiab J5. Txawm hais tias tus nqi sib txawv los ntawm$50 rau $200 ib tujyog qhov chaw, tus nqi qis dua tsis ib txwm txhais mus rau tus nqi qis dua tag nrho. Cov ntsiab lus xws li cov ntsiab lus npib tsib xee, tooj liab piv, sib sib zog nqus- kos duab kev ua tau zoo, kev tiv thaiv corrosion, thiab kev ua haujlwm ruaj khov cuam tshuam ncaj qha rau qhov kawg ntawm cov khoom zoo, cov nqi seem, thiab cov nqi mus sij hawm ntev -.
Dab tsi yog 201 J1 J2 J3 J4 J5 Txias-Rolled Stainless Steel Chev?
201 stainless hlau txias- dov kauj yog ib qho kev lag luam austenitic alloy (tus cwj pwm los ntawm cov ntsiab lus tsis tshua muaj npib tsib xee thiab cov manganese siab) ua rau hauv daim ntawv loj, txuas ntxiv. Cov npe J1, J2, J3, J4, thiab J5 sawv cev rau cov qauv sub-qib cov qauv tsim los ntawm Suav tuam txhab lag luam kom paub qhov txawv ntawm cov pa roj carbon, chromium, thiab tooj liab.
Qhov txawv tseem ceeb:
Cov ntsiab lus tooj liab (siab tshaj plaws rau qis): J4 > J1 > J3 > J2 > J5. Cov ntsiab lus tooj liab siab dua txhim kho cov khoom siv ductility thiab sib sib zog nqus - kos duab muaj peev xwm.
Cov ntsiab lus carbon (siab tshaj plaws rau qis tshaj): J5 > J2 > J3 > J1 > J4. Cov ntsiab lus carbon ntau dua ua rau cov khoom siv hardness thiab lub zog, tab sis txo nws cov formability thiab corrosion kuj.
Hardness (siab tshaj mus rau qis tshaj): J5, J2> J3> J1> J4. Qib J2 thiab J5 muaj hardness ntau dua thiab yog cov nkig ntau dua, ua rau lawv tsim nyog rau kev tsim cov ntawv tiaj tus thiab cov khoom siv nrog cov geometry yooj yim.
Nqe (siab tshaj mus rau qis tshaj): J4 > J1 > J3 > J2, J5. Qib J4 yog qhov kim tshaj plaws vim nws cov ntsiab lus tooj liab ntau dua.

Vim li cas tus nqi sib txawv ntawm J1 thiab J5?
Thawj tus nqi tsav tsheb yog tooj liab (Cu) cov ntsiab lus.
J1 (High Copper): Ntau dua ductility thiab "sib sib zog nqus nqus" muaj peev xwm. Nws tso cai rau cov hlau txuas mus rau hauv cov duab nyuaj (xws li lub lauj kaub lossis dab dej) yam tsis muaj kev tawg. Qhov no ua rau nws kim tshaj plaws hauv tsev neeg 201.
J2/J5 (Low Copper/High Manganese): Cov no yog "Economy Grade." Lawv nyuaj thiab nkig ntau dua. Thaum zoo heev rau cov vaj huam sib luag tiaj tus lossis cov raj yooj yim, lawv tsis haum rau kev sib sib zog nqus ncab. Vim tias lawv siv tooj liab tsawg, tus nqi qis dua.
Thaum thov ib qho kev tsocai, nco ntsoov qhia qhov tseeb Thickness thiab Copper Content Requirement. Piv txwv li: "Quote rau 201 J1 Cold Rolled Coil, 2B tiav, 0.5mm tiag tiag, 1219mm Dav, Copper> 0.8%.

Yuav ua li cas kom tau txais 201 Stainless Hlau Coils?
Muaj cov xwm txheej hauv kev ua lag luam uas J5 cov khoom raug muag tsis raug raws li J1. J5 muaj cov ntsiab lus ntawm manganese siab heev. Txawm hais tias nws muaj zog dua, nws cov tawv tawv tsis zoo, thiab nws muaj feem ntau yuav tawg thaum lub sij hawm sib sib zog nqus nqus los yog tsim cov txheej txheem. Thaum yuav khoom, nws raug nquahu kom thov daim ntawv pov thawj Mill Test (MTC) los ntawm lub zeb zeb lossis siv lub spectrometer los xyuas cov ntsiab lus tooj liab ntawm -site.
1. Thickness Tolerance (Thickness Tolerance)
201 txias- dov stainless hlau coils feem ntau yog muag los ntawm kev ntsuas qhov hnyav lossis qhov hnyav tiag tiag. Thaum tham txog tus nqi, nco ntsoov paub meej tias qhov tseeb thickness kam rau ua. Piv txwv li, rau lub nominal thickness ntawm 0.5 hli, yog qhov tseeb kam rau ua -0.03 hli los yog -0.05 hli? Txawv tolerances ncaj qha cuam tshuam qhov ntev ntawm ib tuj ntawm cov khoom.
2. Nto Zoo
Feem ntau nto tiav rau txias- dov 201 stainless hlau suav nrog 2B, BA, thiab txhuam tiav. Vim muaj cov ntsiab lus siab manganese hauv 201 stainless hlau, kev ua tsis zoo yuav ua rau cov pob dub lossis xeb ntawm qhov chaw. Cov neeg yuav khoom yuav tsum paub meej tias cov coils tau raug kho kom zoo los ntawm lub tshuab muaj npe nrov.
