430 stainless hlau yog cov hlau dav dav nrog kev ua haujlwm zoo corrosion. Nws cov thermal conductivity yog zoo dua li ntawm austenite, nws coefficient ntawm thermal expansion yog me dua li ntawm austenite, kub qaug zog tsis kam, ntxiv rau stabilizing lub titanium, thiab zoo txhua yam khoom ntawm lub vuam. 430 stainless hlau yog siv rau kev kho kom zoo nkauj hauv tsev, cov khoom siv roj hlawv, cov khoom siv hauv tsev thiab cov khoom siv hauv tsev. 430F yog ib hom hlau nrog kev txiav dawb ntawm 430 steel. Nws yog tsuas yog siv rau cov tshuab dhos tsis siv neeg, bolts thiab ceev. 430lx ntxiv Ti los yog Nb rau 430 steel thiab txo cov ntsiab lus ntawm C, uas txhim kho cov txheej txheem thiab vuam kev ua tau zoo. Nws yog tsuas yog siv nyob rau hauv lub tank dej kub, dej kub system, huv si khoom, khoom siv hauv tsev, tsheb kauj vab flywheel, thiab lwm yam.
Nto qib
430 stainless hlau muaj cov hauv qab no. Txawv lub xeev, av tsis kam thiab corrosion kuj kuj txawv.
No.1, 1D, 2D, 2b, N0.4, HL, Ba, daim iav, thiab lwm yam kev kho deg.
Cov yam ntxwv ua tshuab
1D - discontinuous granular nto, tseem hu ua pos huab. Kev siv thev naus laus zis: kub dov + annealing, tua peening thiab pickling + txias dov + annealing thiab pickling.
2D - me ntsis ci nyiaj dawb. Kev siv thev naus laus zis: kub dov + annealing, tua peening thiab pickling + txias dov + annealing thiab pickling.
2B - silvery dawb thiab zoo dua gloss thiab flatness dua 2D nto. Kev siv thev naus laus zis: kub dov + annealing, tua peening thiab pickling + txias dov + annealing thiab pickling + quenching thiab tempering dov.
BA - zoo heev nto gloss thiab siab reflectivity, ib yam li saum npoo ntawm daim iav. Kev siv thev naus laus zis: kub dov + annealing, tua peening thiab pickling + txias dov + annealing thiab pickling + nto polishing + quenching thiab tempering dov.
NO.3 - nws muaj gloss zoo thiab coarse grain ntawm qhov chaw. Kev siv thev naus laus zis: polishing thiab quenching thiab tempering dov ntawm 2D khoom lossis 2B nrog 100 ~ 120 abrasive cov ntaub ntawv (JIS R6002).
NO.4 - nws muaj cov gloss zoo thiab cov kab zoo ntawm qhov chaw. Kev siv tshuab: polishing thiab quenching thiab tempering dov ntawm 2D lossis 2B nrog 150 ~ 180 abrasive khoom (JIS R6002).
HL - nyiaj grey nrog cov plaub hau kab txaij. Kev siv thev naus laus zis: Polish 2D lossis 2B cov khoom lag luam nrog cov khoom siv abrasive nrog qhov loj me me los ua kom pom cov kab sib tsoo txuas ntxiv.
Mirror - daim iav xeev. Kev siv thev naus laus zis: zom thiab txhuam 2D lossis 2B cov khoom lag luam nrog cov khoom sib tsoo uas tsim nyog rau daim iav nyhuv.
430 stainless hlau muaj peev xwm ntawm oxidation tsis kam mus rau corrosion, tab sis muaj lub siab nyiam ntawm intergranular corrosion.
430 stainless hlau hlau yog dav siv nyob rau hauv axis.
Vim tias nws muaj kev nyab xeeb thiab tsis muaj tshuaj lom, nws tau siv dav hauv cov khoom noj khoom haus.

Kuj tseem muaj cov hlau tsis muaj steel, 201, 202, 203 thiab 204, uas muaj chromium tsawg thiab manganese siab (siab chromium zog nce corrosion kuj, thiab siab manganese tuaj yeem ua rau cov khoom tsis sib nqus). Cov hlau tsis zoo no muaj kev tiv thaiv corrosion tsis zoo thiab feem ntau yog siv rau kev kho kom zoo nkauj ib puag ncig qhuav.
