Yuav ua li cas paub qhov txawv ntawm stainless hlau yog 304 lossis 316?
Tso lus
304 stainless hlau VS 316 tshuaj muaj pes tsawg leeg:
304 stainless hlau feem ntau muaj 18% chromium thiab 8% npib tsib xee, thiab tsis muaj molybdenum; thaum 316 stainless hlau muaj 2% molybdenum ntxiv rau 18% chromium thiab 10% npib tsib xee.
304 stainless hlau VS 316 corrosion kuj:
Vim lub molybdenum caij, 316 stainless hlau ua tau zoo dua nyob rau hauv ib puag ncig uas muaj chloride, tshwj xeeb tshaj yog nyob rau hauv xov xwm nrog cov ntsiab lus chloride ion siab.
304 stainless hlau VS 316 nqe:
Vim tias cov ntsiab lus alloy siab dua thiab cov nqi tsim khoom ntau dua ntawm 316 stainless hlau, nws cov nqi feem ntau kim dua 304 stainless hlau.
304 stainless hlau VS 316 daim ntawv thov thaj chaw:
304 stainless hlau yog dav siv hauv cov khoom siv hauv tsev, kho kom zoo nkauj hauv tsev thiab lwm yam; thaum 316 stainless hlau siv ntau dua hauv cov khoom siv kho mob, cov khoom siv tshuaj, ib puag ncig marine thiab lwm yam xav tau ntau zaus.
Kev sib piv ntawm cov hlau nplaum ntawm 304 thiab 316 stainless hlau
Cov hlau nplaum ntawm 304 stainless hlau: 304 stainless hlau yog austenitic stainless hlau thiab feem ntau suav tias yog cov hlau tsis sib nqus lossis tsuas yog cov hlau nplaum tsis muaj zog.
Magnetism ntawm 316 stainless hlau: Zoo ib yam li 304 stainless hlau, 316 stainless hlau kuj yog austenitic stainless hlau thiab feem ntau tsis yog hlau nplaum. Cov molybdenum thiab ntau dua cov ntsiab lus ntawm nickel ntxiv rau nws cov alloy muaj pes tsawg leeg feem ntau txhim kho nws cov kev tiv thaiv corrosion thiab kub kub lub zog tsis cuam tshuam rau nws cov khoom sib nqus.
Kev kuaj kev tshaj lij: Thaum kuaj nrog cov kws tshaj lij stainless hlau potion, qhov saum npoo ntawm 304 stainless hlau yuav pom cov xim liab, thaum 316 stainless hlau tuaj yeem tshwm dub.
