Qhov sib txawv tseem ceeb ntawm stainless hlau thiab sterling nyiaj yog tias stainless hlau tsis tshua muaj ci thiab ci dua li cov nyiaj sterling, uas muaj qhov ci zoo nkauj heev.
Ib qho hlau yog sib xyaw ntawm ob lossis ntau dua hlau nrog qee yam tshuaj lom neeg. Stainless hlau thiab sterling nyiaj yog ob qho tseem ceeb alloys nrog ntau yam kev siv tseem ceeb. Ob lub alloys no muaj qhov sib txawv, yog li nws tsis yooj yim rau kev paub qhov txawv ntawm ob lub alloys.
Stainless Hlau yog dab tsi?
Stainless hlau yog hom hlau alloy uas muaj 10-30% ntawm chromium. Nws muaj cov ntsiab lus ntawm cov pa roj carbon tsawg, thiab nws cov chromium feem ntau ua rau muaj kev cuam tshuam zoo heev rau corrosion thiab kub. Lwm yam tshuaj xws li npib tsib xee, molybdenum, titanium, txhuas, niobium, tooj liab, nitrogen, thiab lwm yam, kuj tuaj yeem muab ntxiv rau nws. Cov kev ntxiv no ua rau muaj kev tiv thaiv corrosion rau ib puag ncig tshwj xeeb, txhim kho oxidation tsis kam, thiab muab cov yam ntxwv tshwj xeeb.
Muaj txog 100 qib sib txawv ntawm cov hlau tsis muaj steel. Peb tuaj yeem faib cov feem ntau ua tsib pawg loj hu ua austenitic, ferritic, martensitic, duplex, thiab nag lossis daus-hardening.
Feem ntau, stainless hlau yog qhov zoo nkauj, nyiam huv, yooj yim los tuav, ruaj khov, thiab muaj ntau yam. Yog li ntawd, peb tuaj yeem nrhiav stainless hlau hauv cov khoom siv niaj hnub, qhov chaw uas nws ua lub luag haujlwm tseem ceeb hauv kev lag luam xws li lub zog, kev thauj mus los, tsev, kev tshawb fawb, tshuaj, thiab lwm yam.
Austenitic stainless hlau muaj li 21% chromium thiab txog 0.10% carbon, nrog rau qee yam tshuaj lom neeg. Cov ntawv thov ntawm cov khoom siv no suav nrog kev lag luam boiler, cov khoom siv hluav taws xob, cov khoom siv tsheb ciav hlau, cov raj, cov tso tsheb hlau luam, thiab lwm yam.
Lwm hom hlau stainless feem ntau yog ferritic stainless hlau. Nws muaj li ntawm 30% chromium thiab 0.06% carbon. Nws yog ib qho tseem ceeb hauv kev siv xws li lub tshuab tso tsheb, cov khoom siv ua noj, boilers, cov khoom siv hauv tsev, thiab lwm yam.
Sterling Silver yog dab tsi?
Sterling nyiaj yog ib hom hlau ntawm cov nyiaj uas muaj li ntawm 92% ntawm nws qhov hnyav hauv nyiaj thiab lwm yam hlau. Feem ntau, zoo nyiaj muaj li 99% purity. Cov nyiaj zoo kuj yog mos, yog li nws feem ntau yog alloyed nrog lwm yam hlau xws li tooj liab kom nws hardness thiab zog. Tsis tas li ntawd, cov hlau no feem ntau ua rau tarnishing, thiab peb tuaj yeem siv cov hlau uas tsis yog tooj liab los txo cov nyhuv tarnishing. Tsis tas li ntawd, peb tuaj yeem ntxiv lwm yam tshuaj lom neeg rau cam khwb cia porosity thiab firescale. Cov ntsiab lus tshuaj uas peb tuaj yeem siv hauv cov ntsiab lus no suav nrog germanium, zinc, platinum, silicon, thiab boron.
Muaj ntau yam kev siv nyiaj sterling, suav nrog kev tsim cov diav rawg xws li cov diav rawg noj hmo, diav rawg, ncuav qab zib diav, diav xws li teaspoons, kas fes diav, iced tshuaj yej diav, thiab riam xws li riam noj hmo, butter spreaders, cheese riam, etc.
Hauv cov ntsiab lus tshuaj, nyiaj tsis yog hlau ntau ntau. Qhov no txhais tau tias nws tsis hnov mob nrog oxygen lossis dej ntawm qhov kub thiab txias; yog li ntawd, nws tsis tsim nyiaj oxide yooj yim. Txawm li cas los xij, cov khoom siv hauv huab cua muaj kuab paug tuaj yeem tua cov hlau no yooj yim. Piv txwv li, thaum raug cov huab cua sib xyaw sulfur, cov nyiaj ua cov nyiaj sulfide, uas zoo li cov xim dub. Yog li ntawd, qhov txo qis hauv purity ntawm cov nyiaj yuav ua rau tus nqi siab dua ntawm corrosion los yog tarnishing. Tsis tas li ntawd, lwm cov hlau hauv cov hlau xws li tooj liab tuaj yeem hnov mob nrog oxygen hauv huab cua.
Qhov txawv ntawm Stainless Hlau thiab Sterling Silver yog dab tsi?
Qhov sib txawv tseem ceeb ntawm stainless hlau thiab sterling nyiaj yog tias stainless hlau tsis tshua muaj ci thiab ci, thaum sterling nyiaj muaj qhov ci zoo nkauj heev. Ntxiv mus, qhov hnyav ntawm stainless hlau yog siab dua li ntawm cov nyiaj sterling.
Summary – Stainless hlau vs Sterling Silver
Stainless steel yog hom hlau alloy uas muaj 10-30% ntawm chromium, thaum sterling nyiaj yog hom hlau ntawm cov nyiaj muaj li ntawm 92% ntawm nws qhov hnyav nrog nyiaj thiab lwm yam hlau. Qhov sib txawv tseem ceeb ntawm cov hlau tsis muaj hlau thiab cov nyiaj sterling yog cov hlau tsis muaj xim tsis tshua muaj ci thiab ci dua li cov nyiaj sterling, uas muaj qhov ci zoo nkauj heev.
