Stainless hlau yog ib qho nyuaj tshaj li cov hlau ntshiab vim muaj ntau yam, feem ntau muaj feem xyuam rau nws cov muaj pes tsawg leeg thiab kev ua. Ntawm no yog cov laj thawj tseem ceeb vim li cas cov hlau tsis muaj steel muaj zog dua piv rau cov hlau ntshiab:
Chromium Cov ntsiab lus:
Stainless hlau yog ib qho hlau uas muaj hlau ua nws lub hauv paus, tab sis nws kuj suav nrog cov nyiaj chromium tseem ceeb, nrog rau lwm cov ntsiab lus xws li npib tsib xee, carbon, thiab qee zaum molybdenum.
Chromium plays lub luag haujlwm tseem ceeb hauv kev nce hardness ntawm stainless hlau. Nws tsim ib txheej tuab ntawm chromium oxide nyob rau saum npoo ntawm cov hlau, uas tsis tsuas yog muab kev tiv thaiv corrosion, tab sis kuj txhim kho nws cov hardness.
Alloying Elements:
Qhov sib ntxiv ntawm lwm yam alloying ntsiab, xws li npib tsib xee thiab molybdenum, ntxiv dag zog rau cov hlau tsis muaj steel thiab pab txhawb rau nws hardness. Cov ntsiab lus no tuaj yeem hloov kho cov qauv siv lead ua ntawm cov hlau thiab tsim cov sib txuas sib txuas uas ua rau nws lub zog tag nrho.
Crystal Structure:
Cov qauv siv lead ua ntawm stainless hlau feem ntau yog qhov nyuaj thiab txiav txim siab dua li cov hlau ntshiab. Qhov kev nyuaj no ua rau cov khoom siv hardness los ntawm kev ua rau nws nyuaj rau cov atoms swb ib leeg nyob rau sab nraud.
Kev kho cua sov:
Stainless hlau tuaj yeem dhau los ua ntau yam kev kho cua sov, xws li quenching thiab tempering, ntxiv rau nws cov hardness ntxiv. Cov txheej txheem no hloov cov microstructure ntawm cov hlau, ua rau nws tiv taus ntau deformation thiab hnav.
Ua haujlwm txias:
Cov txheej txheem ua haujlwm txias, xws li dov, kos duab, lossis forging, kuj tuaj yeem ua rau cov hlau tsis muaj zog los ntawm kev qhia txog kev tsis sib haum xeeb thiab strain hardening hauv cov khoom.
Hauv cov ntsiab lus, stainless hlau yog ib qho nyuaj dua li cov hlau ntshiab vim nws cov ntsiab lus chromium siab, qhov sib ntxiv ntawm lwm cov khoom siv alloying, nws cov qauv siv lead ua nyuaj, thiab kev kho cua sov thiab cov txheej txheem ua haujlwm txias uas nws dhau mus. Cov yam tseem ceeb no ua rau cov khoom muaj zog ntxiv, ua rau nws tsim nyog rau cov ntawv thov uas xav tau kev hnav, deformation, thiab corrosion.
