410S 420J2 430 Kub-Rolled Stainless Steel Coils Nqe

Ntau tus neeg yuav khoom xav tias tus nqi ntawm tag nrho cov hlau stainless coils yuav tsum yog tib yam. Txawm li cas los xij, hauv kev ua lag luam niaj hnub no, tus nqi sib txawv ntawm 410S, 420J2, thiab 430 kub- dov stainless hlau coils tuaj yeem muaj li ntawm $ 400 txog $ 800 toj ib tuj, nyob ntawm seb muaj pes tsawg leeg, cov kev xav tau ntawm hardness, dov txheej txheem, thiab cov kev xav tau ntawm cov khoom siv qis.

Piv txwv li, cov tuam txhab tsim khoom siv hauv chav ua noj yuav xaiv 430 stainless hlau rau nws cov qauv zoo heev thiab tus nqi qis, thaum cov tuam txhab cutlery yuav xaiv rau 420J2 vim nws cov hardness superior thiab hnav tsis kam. Xaiv qhov tsis ncaj ncees lawm qib tsis tuaj yeem nce cov nqi khoom siv thiab txo cov khoom lag luam tab sis tseem tuaj yeem ua rau cov khoom lag luam ntxov ntxov.

Muab qhov tsis hloov pauv ntawm cov nqi ntawm cov khoom siv raw thiab hloov cov kev xav tau thoob ntiaj teb, nws yog qhov tseem ceeb rau kev yuav cov thawj coj, cov neeg xa khoom, thiab cov tuam txhab lag luam kom nkag siab zoo txog cov qauv nqi cuam tshuam nrog 410S, 420J2, thiab 430 stainless hlau coils.

410S, 420J2, thiab 430: Cov qib twg yog qhov pheej yig tshaj?

Ntawm peb qib no, 410S feem ntau muaj tus nqi qis tshaj, ua raws li 430, thaum 420J2 feem ntau hais kom tus nqi siab tshaj. Tus nqi FOB feem ntau rau Suav - tsim kub- dov coils yog raws li hauv qab no: $ 1,300– $ 1,650 / tonne rau 410S, $ 1,450– $ 1,850 / tonne rau 430, thiab $ 1,800– $ 2,400 / tonne rau.42

Vim li cas tus nqi ntawm 420J2 siab dua li ntawm 430?

Txawm hais tias ob qib muaj nyob rau hauv 400 series ntawm stainless hlau, 420J2 muaj cov pa roj carbon ntau dua (feem ntau 0.26% - 0.40%), whereas 430 muaj 0.12% lossis tsawg dua. Cov pa roj carbon ntau dua no tso cai rau 420J2 kom ua tiav qhov hardness ntawm 48-55 HRC tom qab kev kho cua sov; Nyob rau hauv sib piv, 430 feem ntau muaj ib tug hardness qis dua 20 HRC thiab tsis tuaj yeem hardened los ntawm quenching. Yog li ntawd, tus nqi ntawm 420J2 steel coils feem ntau yog 15% -35% siab dua li ntawm 430 coils, tshwj xeeb tshaj yog thaum siv rau kev tsim cutlery, hniav, cov cuab yeej phais, thiab hnav- cov khoom tiv thaiv.

410S, 420J2, thiab 430: Qhov twg muaj kev hnav zoo dua?

420J2 muab qhov zoo tshaj plaws hnav tsis kam los ntawm cov npoo loj heev. Tom qab kev kho cua sov kom zoo, nws qhov nyuaj tuaj yeem ncav cuag 48-55 HRC, ua rau nws tsim nyog rau kev txiav cov cuab yeej, txiab, riam, thiab cov khoom siv coj los siv. Los ntawm kev sib piv, 410S thiab 430 feem ntau pom qhov tseem ceeb hardness qis dua 95 HRB (kwv yees li 18-20 HRC sib npaug) hauv qhov mob annealed. Kev sim hnav hauv kev siv cov cuab yeej siv feem ntau qhia tau hais tias hardened 420J2 Cheebtsam tuaj yeem ua tiav ob mus rau plaub npaug ntawm kev pabcuam lub neej ntawm qhov sib npaug 430 cov khoom nyob rau hauv abrasive tej yam kev mob. Yog li ntawd, thaum tsis kam mus khawb, txiav- ntug hnav, lossis kev puas tsuaj yog qhov kev txhawj xeeb tseem ceeb, 420J2 feem ntau yog qhov kev xaiv.

410S, 420J2, thiab 430: Qhov twg yog qhov zoo dua rau stamping?

Hom 430 stainless hlau feem ntau yog qhov kev xaiv zoo tshaj plaws rau kev sib sib zog nqus- kos duab thiab stamping daim ntawv thov. Nrog rau cov ntsiab lus chromium ntawm kwv yees li 16% -18%, nws muaj cov ductility zoo thiab ua haujlwm zoo ib yam, ua rau nws siv dav hauv kev tsim cov dab dej hauv chav ua noj, cookware, tshuab ntxhua khaub ncaws, cov khoom siv vaj huam sib luag, thiab cov khoom siv kho kom zoo nkauj. Hauv qhov sib piv, Hom 420J2-vim nws cov ntsiab lus carbon ntau dua thiab qis dua ductility{14}} ua rau muaj kev pheej hmoo ntau dua ntawm kev tawg thaum lub sijhawm ua haujlwm hnyav. Thaum Hom 410S outperforms Hom 420J2, nws qhov kev ua haujlwm stamping feem ntau tseem poob qis ntawm Hom 430. Hauv kev tsim cov khoom siv loj, kev siv hom 430 stainless hlau feem ntau tuaj yeem txo tus nqi stamping los ntawm 10% -20% piv rau cov pa roj carbon ntau.
