Dab tsi yog qhov txawv ntawm Stainless Hlau 304 thiab 321 Khoom

Dab tsi yog qhov txawv ntawm stainless hlau 304 thiab 321 khoom

Ua ntej, qhov xwm txheej txawv

1, 321 stainless hlau: Nws yog Ni-Cr-Ti austenitic stainless hlau. 321 stainless hlau yog Ni-Cr-Ti austenitic stainless hlau, nws cov kev ua tau zoo heev zoo ib yam li 304, tab sis vim yog ntxiv ntawm titanium hlau, thiaj li hais tias nws muaj kev tiv thaiv zoo rau grain ciam corrosion thiab kub siab zog. Vim qhov sib ntxiv ntawm titanium hlau, nws tswj tau qhov tsim ntawm chromium carbide.

2, 304 stainless hlau: Nws yog cov khoom siv hauv cov hlau tsis muaj steel, qhov ntom ntom yog 7.93g / cm3, hom kev kos npe hauv khw yog 06Cr19Ni10, SUS304.
 

Thib ob, cov yam ntxwv sib txawv

1, 321 stainless hlau: nrog rau kev puas tsuaj, kub tsis kam, nkag tsis kam thiab lwm yam. Lub Ti ntawm 321 stainless hlau muaj nyob rau hauv cov khoom ruaj khov, tab sis nws kuj yog qib kub-lub zog steel, uas zoo dua li 316L nyob rau hauv qhov kub thiab txias, thiab 321 stainless hlau yog nyob rau hauv cov organic thiab inorganic acids sib txawv concentrations thiab kub.

2, 304 stainless hlau: qhov tseem ceeb tshaj plaws ntawm 304 yog Ni, Cr, tab sis tsis txwv rau ob lub ntsiab lus. Cov kev cai tshwj xeeb yog teev los ntawm cov qauv khoom. Qhov teeb meem kev txiav txim siab hauv kev lag luam ntseeg tias ntev npaum li cov ntsiab lus Ni yog siab dua 8% thiab cov ntsiab lus Cr ntau dua 18%, nws tuaj yeem suav tias yog 304 stainless hlau.

Peb, kev siv sib txawv

1, 321 stainless hlau: siv los tsim cov khoom hnav-resistant acid ntim thiab hnav-resistant cov ntaub ntawv, conveying kav. Nws yog siv nyob rau hauv chemical, thee thiab roj av kev lag luam nrog siab grain ciam teb corrosion kuj, tshav kub resistant qhov chaw ntawm lub tsev cov ntaub ntawv thiab qhov chaw uas muaj teeb meem nyob rau hauv kev kho cua sov.

2, 304 stainless hlau: dav siv hauv kev lag luam thiab rooj tog kho kom zoo nkauj kev lag luam thiab khoom noj khoom haus thiab kev kho mob kev lag luam.
