Stainless Hlau Round Bar Nrog Zoo Zoo
Kev sib xyaw ua ke
Hlau (Fe): yog cov hlau tseem ceeb ntawm stainless hlau;
Chromium (Cr): yog lub ntsiab ferrite tsim cov khoom, chromium ua ke nrog oxygen tuaj yeem tsim cov tshuaj tiv thaiv corrosion-resistant Cr2O3 passivation zaj duab xis, yog ib qho ntawm cov ntsiab lus ntawm stainless hlau kom muaj kev tiv thaiv corrosion, chromium cov ntsiab lus ua rau cov khoom siv passivation kho muaj peev xwm ntawm cov hlau, cov ntsiab lus stainless hlau chromium yuav tsum siab tshaj 12%;
Cov pa roj carbon (C): yog qhov muaj zog austenite tsim, tuaj yeem txhim kho lub zog ntawm cov hlau, ntxiv rau cov pa roj carbon monoxide kuj muaj qhov cuam tshuam tsis zoo;
Nickel (Ni): yog lub ntsiab austenite tsim cov khoom, tuaj yeem ua kom qeeb ntawm cov hlau thiab kev loj hlob ntawm cov nplej thaum cua sov;
Molybdenum (Mo): yog cov carbide tsim cov khoom, cov carbide tsim yog qhov ruaj khov heev, tuaj yeem tiv thaiv kev loj hlob ntawm austenite thaum rhuab, txo cov superheat rhiab heev ntawm cov hlau, ntxiv rau, molybdenum tuaj yeem ua rau cov zaj duab xis passivation ntau ntom thiab ruaj khov, yog li txhim kho cov hlau stainless Cl- corrosion kuj;
Niobium, titanium (Nb, Ti): yog ib qho muaj zog carbide tsim cov ntsiab lus, tuaj yeem txhim kho cov hlau tsis kam rau intergranular corrosion. Txawm li cas los xij, titanium carbide muaj qhov cuam tshuam tsis zoo rau qhov zoo ntawm cov hlau tsis zoo, yog li cov hlau tsis muaj hlau nrog cov kev xav tau saum npoo siab feem ntau txhim kho los ntawm kev ntxiv niobium los txhim kho kev ua haujlwm.
Nitrogen (N): yog lub zog austenite tsim, tuaj yeem txhim kho lub zog ntawm cov hlau. Tab sis kev laus tawg ntawm stainless hlau muaj kev cuam tshuam ntau dua, yog li cov hlau tsis huv hauv stamping lub hom phiaj kom nruj tswj cov ntsiab lus nitrogen.
Phosphorus, sulfur (P, S): yog ib qho teeb meem nyob rau hauv stainless hlau, corrosion kuj thiab stamping stainless hlau yuav muaj kev cuam tshuam tsis zoo.
Khoom Qhia
Khoom siv thiab kev ua haujlwm
| Khoom siv | Yam ntxwv |
| 310S stainless hlau | 310S stainless hlau yog austenitic chromium-nickel stainless hlau nrog zoo oxidation tsis kam, corrosion kuj, vim hais tias ntawm cov feem pua ntawm cov chromium thiab npib tsib xee, 310S muaj zog nkag tau zoo dua, tuaj yeem ua haujlwm ntawm qhov kub thiab txias, nrog rau qhov kub thiab txias. |
| 316L stainless hlau round bar | 1) Zoo glossy thiab zoo nkauj tsos ntawm cov khoom txias dov. 2) zoo heev corrosion kuj, tshwj xeeb tshaj yog pitting kuj, vim qhov sib ntxiv ntawm Mo 3) zoo heev kub lub zog; 4) zoo heev ua hauj lwm hardening (tsis muaj zog hlau nplaum tom qab ua) 5) non-magnetic nyob rau hauv lub xeev cov tshuaj. |
| 316 stainless hlau round hlau | Cov yam ntxwv: 316 stainless hlau yog qhov thib ob feem ntau siv hlau tom qab 304, feem ntau yog siv hauv kev lag luam khoom noj thiab cov khoom siv phais, vim tias qhov sib ntxiv ntawm Mo, yog li nws cov kev tiv thaiv corrosion, atmospheric corrosion kuj thiab kub lub zog yog tshwj xeeb tshaj yog zoo, yuav siv tau nyob rau hauv hnyav tej yam kev mob; zoo heev ua hauj lwm hardening (tsis-magnetic). |
| 321 stainless hlau round steel | Cov yam ntxwv: Qhov sib ntxiv ntawm Ti ntsiab rau 304 steel los tiv thaiv kab lis kev cai corrosion, haum rau siv ntawm qhov kub ntawm 430 ℃ - 900 ℃. Lwm yam tshaj li qhov sib ntxiv ntawm cov ntsiab lus titanium kom txo tau qhov kev pheej hmoo ntawm cov khoom siv vuam corrosion lwm yam khoom zoo ib yam li 304 |
| 304L stainless hlau puag ncig | 304L stainless hlau puag ncig yog ib qho txawv ntawm 304 stainless hlau nrog cov ntsiab lus qis dua thiab siv rau hauv cov ntawv thov uas yuav tsum tau vuam. Cov ntsiab lus qis dua txo qis cov nag lossis daus ntawm carbide hauv thaj chaw tshav kub uas cuam tshuam ze rau qhov vuam, uas tuaj yeem ua rau muaj kev cuam tshuam ntawm intergranular corrosion (weld erosion) ntawm stainless hlau hauv qee qhov chaw. |
| 304 stainless hlau round hlau | Cov yam ntxwv: 304 stainless hlau yog ib qho ntawm feem ntau siv chromium-nickel stainless hlau, nrog zoo corrosion kuj, kub tsis kam, kub tsis tshua muaj zog thiab txhua yam khoom. Corrosion kuj nyob rau hauv cov huab cua, yog hais tias lub industrial cua los yog hnyav hnyav, nws yuav tsum tau muab ntxuav nyob rau hauv lub sij hawm kom tsis txhob muaj corrosion. |
