Raws li peb txhua tus paub, qhov kev tiv thaiv corrosion ntawm stainless hlau nyob ntawm nws cov alloy muaj pes tsawg leeg (chromium, nickel, carbon, silicon, manganese, thiab lwm yam) thiab lub koom haum sab hauv, lub luag haujlwm txiav txim siab yog ua los ntawm chromium alloy caij, uas tuaj yeem tsim ib qho passivation. zaj duab xis nyob rau saum npoo ntawm cov hlau, yog li cov hlau raug cais tawm ntawm lub ntiaj teb sab nraud thiab yuav tsis tsim cov tshuaj tiv thaiv oxidation los txhim kho corrosion kuj ntawm hlau, yog li lwm lub npe rau stainless hlau yog chromium-nickel alloy hlau.
8K nyob rau hauv "8" yog hais txog kev faib ua feem ntawm cov hlau alloy muaj pes tsawg leeg (304 stainless hlau feem ntau yog hais txog cov ntsiab lus ntawm nickel ntsiab), "K" yog hais txog polished reflectivity ntawm qib (K yog daim iav reflective qib). 8K daim iav kuj yog chromium-nickel alloy steel embodied nyob rau hauv daim iav qib.
Tsis tas li ntawd, vim yog cov kev xav tau sib txawv ntawm cov neeg siv khoom rau qhov zoo nkauj ntawm cov hlau tsis muaj steel, ntawm lub hauv paus ntawm 8K txuas ntxiv 6K, 10K, 12K, thiab lwm yam .. Thiab qhov loj dua, qhov siab dua daim iav fineness. 6K hais txog kev sib tsoo ntxhib thiab polishing daim iav phaj, nws cov nyhuv yog me ntsis phem dua daim iav; 10K hais txog kev sib tsoo zoo thiab polishing daim iav phaj, piv rau cov iav zoo tib yam; 12K hais txog ultra-nplua degree sib tsoo thiab polishing daim iav phaj, tuaj yeem ua tau raws li lub hom phiaj kho qhov muag.
Txawm li cas los xij, tsis muaj teeb meem dab tsi ntawm qhov zoo nkauj, uas stainless hlau daim iav phaj, txog tam sim no tsis muaj kev sib koom ua ke, tsuas yog qhov siab dua qhov ci, qhov ntau dua qhov kev xav, qhov tsis xws luag ntawm qhov chaw (dawb me ntsis, pinhole, txiv kab ntxwv tev qauv, dej ripples, thiab lwm yam), qhov ntau nws tuaj yeem lees paub los ntawm cov neeg siv khoom.
