Qhov sib txawv ntawm Stainless Hlau 304 Thiab 321 Hlau Yeeb Nkab

1. Cov khoom sib txawv
1. 321 stainless hlau: Nws yog Ni-Cr-Ti austenitic stainless hlau. 321 stainless hlau yog Ni-Cr-Ti austenitic stainless hlau. Nws qhov kev ua tau zoo zoo ib yam li ntawm 304, tab sis vim yog qhov sib ntxiv ntawm cov hlau titanium, nws muaj kev tiv thaiv zoo rau grain ciam corrosion thiab kub siab zog. Qhov sib ntxiv ntawm cov hlau titanium zoo tswj qhov tsim ntawm chromium carbide.
2. 304 stainless hlau: Nws yog ib qho khoom siv hauv stainless hlau nrog qhov ntom ntawm 7.93g / cm3. Cov txheej txheem cim kev lag luam muaj xws li 06Cr19Ni10 thiab SUS304.
2. Cov yam ntxwv sib txawv
1. 321 stainless hlau: Nws muaj kev tiv thaiv corrosion, kub tsis kam, creep tsis kam, thiab lwm yam. Ti hauv 321 stainless hlau muaj nyob rau hauv cov khoom stabilizing, tab sis nws kuj yog cov cua sov-lub zog steel, uas yog zoo dua li 316L nyob rau hauv cov nqe lus ntawm kub kub. 321 stainless hlau yog nyob rau hauv cov organic acids thiab inorganic acids ntawm txawv concentrations thiab kub.
2. 304 stainless hlau: Cov ntsiab lus tseem ceeb tshaj plaws hauv 304 yog Ni thiab Cr, tab sis lawv tsis txwv rau ob lub ntsiab lus no. Cov kev cai tshwj xeeb yog teev los ntawm cov qauv khoom. Ib qho kev txiav txim siab hauv kev lag luam yog tias ntev npaum li cov ntsiab lus Ni ntau dua 8% thiab cov ntsiab lus Cr ntau dua 18%, nws tuaj yeem suav tias yog 304 stainless hlau.
3. Kev siv sib txawv
1. 321 stainless hlau: siv los tsim cov khoom hnav-resistant acid ntim thiab hauv ob sab phlu thiab cov kav dej rau cov khoom siv hnav-resistant. Nws yog siv rau sab nraum zoov cov cav tov nyob rau hauv cov tshuaj, thee, thiab roj av industries uas yuav tsum tau muaj siab tsis kam mus rau grain ciam corrosion, raws li zoo raws li tshav kub-resistant lub tsev cov khoom thiab qhov chaw uas nyuaj rau kev kho cua sov.
2. 304 stainless hlau: dav siv nyob rau hauv industrial thiab rooj tog kho kom zoo nkauj industries thiab khoom noj khoom haus thiab kev kho mob industries.
