Qhov Tseem Ceeb Qhov txawv - Chrome vs Stainless Hlau
Chrome thiab stainless hlau yog ob qho ntawm cov khoom siv hlau siv ntau tshaj plaws hauv kev tsim cov khoom siv hlau lossis khoom siv. Txawm hais tias ob qho khoom siv no zoo sib xws thiab muaj cov khoom zoo sib xws, lawv txawv heev. Qhov sib txawv ntawm lawv cov khoom thiab kev siv tau tshwm sim vim tias ob cov ntaub ntawv no sib txawv heev hauv lawv cov muaj pes tsawg leeg. Stainless hlau yog cov hlau alloy uas feem ntau muaj hlau, carbon, thiab chromium whereas chrome yog cov khoom siv chromium plated, thiab tsis tuaj yeem suav tias yog cov hlau alloy. Qhov no yog qhov sib txawv tseem ceeb ntawm Chrome thiab Stainless Hlau.
Chrome yog dab tsi?
Chrome yog daim ntawv luv ntawm chromium, thiab nws feem ntau yog hais txog chromium plating. Chromium plating yog daim ntawv thov ntawm txheej chromium rau saum npoo ntawm cov khoom yas lossis hlau los ntawm electroplating. Cov txheej txheem no yog siv rau kev kho kom zoo nkauj thiab kev lag luam. Hauv kev siv cov hniav, nws ntxiv dag zog rau cov khoom ntxiv rau nws cov khoom zoo nkauj. Ib qho piv txwv feem ntau yog chromium plating ntawm ib sab ntawm lub maus taus. Piston rods yog ib qho piv txwv rau kev lag luam daim ntawv thov ntawm chromium plating. Chromium paub zoo rau nws cov luster thiab corrosion kuj.
Stainless Hlau yog dab tsi?
Stainless hlau yog ib qho alloy ua los ntawm cov hlau thiab chromium; Qhov tsawg kawg nkaus kom muaj nuj nqis ntawm chromium yog li 10.5% los ntawm huab hwm coj. Stainless hlau muaj qee qhov tseem ceeb thiab ntau yam khoom xws li tus nqi qis, siab zog, siab dua tiv taus staining, corrosion thiab rusting nrog rau nws cov luster flashier. Muaj peb hom kev lag luam qib stainless hlau ntau yam raws li lawv cov muaj pes tsawg leeg; austenitic, martensitic thiab ferritic. Austenitic yog chromium-nickel-hlau alloy (Cr-16% -26%, Ni -6% -22 thiab cov ntsiab lus qis), Martensitic yog chromium-hlau alloy (Cr-10.5% -17% nrog qee cov ntsiab lus carbon.) thiab Ferritic yog chromium-hlau alloy (Cr- 17% -27% thiab cov ntsiab lus qis carbon). Ntau yam khoom siv ua noj yog tsim los ntawm ferritic hom stainless hlau.
Qhov txawv ntawm Chrome thiab Stainless Hlau yog dab tsi?
Composition:
Chrome: Chrome tsuas muaj chromium xwb; nws tsis yog alloy.
Stainless hlau: Stainless hlau yog ib qho hlau uas muaj tsawg kawg yog 10.5% ntawm chromium ntxiv rau hlau thiab carbon. Tej zaum nws yuav los yog tsis muaj nickel. Kev siv cov npib tsib xee tsawg heev vim nws yog ib qho ntawm cov khoom siv kim tshaj plaws.
Properties:
Chrome: Lub siab ci ntawm Chrome ua rau nws zoo nkauj dua. Txawm li cas los xij, cov khoom siv chrome yog qhov cuam tshuam rau cov av thiab grime. Nws yog qhov sib piv qis dua li cov hlau tsis muaj steel, tab sis cov kav ntev yog qis.
Stainless steel: Lub durability ntawm stainless hlau yog kuj siab dua chrome vim nws yog ib tug alloy. Tsis tas li ntawd, nws yog me ntsis resistant rau corrosion thiab khawb; yog li ntawd, nws tsis tarnish thiab yooj yim heev los ntxuav. Txawm li cas los xij, nws kim heev thiab tsis ci ntsa iab piv rau chrome.
Siv:
Chrome: Khoom chrome (chrome li tib lub caij) tsis yog siv los tsim cov khoom. Hloov chaw, nws yog siv los ua ib txheej nyias ntawm cov khoom uas ua los ntawm cov hlau thiab qee zaum txhuas, tooj dag, tooj liab, yas, lossis stainless hlau.
Stainless steel: Stainless hlau yog siv rau hauv cov khoom siv hauv chav ua noj xws li cutlery, dab dej, saucepans, tshuab ntxhua khaub ncaws, microwave qhov cub liner, rab chais hniav. Nws kuj tseem siv rau hauv engineering engineering los tsim cov qhov rais fittings, cov rooj tog hauv kev, cov khoom siv, cov khoom siv ntxiv, cov teeb pom kev zoo, lintels thiab masonry txhawb nqa. Tsis tas li ntawd, nws yog siv rau hauv kev thauj mus los los tsim cov tshuab tso pa, tsheb trim / grilles, txoj kev tankers, nkoj ntim khoom thiab tshuaj tankers hauv nkoj. Stainless hlau kuj tseem siv rau ntau qhov chaw xws li cov khoom siv roj thiab roj, cov cuab yeej phais, khoom noj khoom haus, brewing, distilling, ua zaub mov,
