Feem ntau, cov hlau stainless hlau yog ib lo lus dav dav rau cov hlau stainless hlau thiab cov hlau uas tiv taus kua qaub. Thaum pib ntawm lub xyoo pua no, kev tsim cov hlau stainless hlau tau tsim ib lub hauv paus tseem ceeb rau kev txhim kho kev lag luam niaj hnub thiab kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis. Muaj ntau hom hlau stainless hlau uas muaj cov yam ntxwv sib txawv, thiab nws tau maj mam tsim ntau pawg hauv cov txheej txheem tsim kho. Raws li cov qauv, nws muab faib ua plaub pawg: hlau stainless hlau austenitic, hlau stainless hlau martensitic (xws li hlau stainless hlau uas tiv taus dej nag), hlau stainless hlau ferritic, thiab hlau stainless hlau austenitic ferritic duplex. Raws li cov tshuaj lom neeg tseem ceeb ntawm cov hlau lossis qee yam ntxwv hauv cov hlau, faib ua hlau chromium, hlau stainless hlau chromium nickel, hlau stainless hlau chromium nickel molybdenum thiab hlau stainless hlau qis carbon, hlau stainless hlau siab molybdenum, hlau stainless hlau siab purity thiab lwm yam. Raws li cov yam ntxwv kev ua tau zoo thiab kev siv ntawm cov hlau phaj, nws muab faib ua cov hlau stainless hlau uas tiv taus nitric acid, cov hlau stainless hlau uas tiv taus sulfuric acid, cov hlau stainless hlau uas tsis tawg, cov hlau stainless hlau uas tiv taus kev ntxhov siab, cov hlau stainless hlau uas muaj zog siab thiab lwm yam. Raws li cov yam ntxwv kev ua haujlwm ntawm cov hlau phaj, nws muab faib ua cov hlau stainless hlau uas tsis kub heev, cov hlau stainless hlau uas tsis muaj hlau nplaum, cov hlau stainless hlau uas yooj yim txiav, cov hlau stainless hlau uas ua los ntawm cov yas zoo heev. Txoj kev faib tawm uas siv ntau yog faib ua raws li cov yam ntxwv ntawm cov hlau phaj thiab cov yam ntxwv ntawm cov hlau phaj thiab kev sib xyaw ua ke ntawm ob txoj kev. Feem ntau muab faib ua cov hlau stainless hlau martensitic, cov hlau stainless hlau ferritic, cov hlau stainless hlau austenitic, cov hlau stainless hlau duplex thiab cov hlau stainless hlau uas tiv taus dej nag lossis muab faib ua cov hlau stainless hlau chromium thiab cov hlau stainless hlau nickel ob pawg. Kev siv ib txwm muaj: cov khoom siv pulp thiab ntawv, cov khoom siv hloov pauv cua sov, cov khoom siv kho tshuab, cov khoom siv zas xim, cov khoom siv ntxuav zaj duab xis, cov kav dej, cov khoom siv sab nraud ntawm thaj chaw ntug dej hiav txwv, thiab lwm yam.
Qhov saum npoo ntawm cov hlau stainless hlau yog du, muaj kev ywj pheej siab, tawv thiab lub zog kho tshuab, thiab tiv taus cov kua qaub, alkaline roj, cov kua thiab lwm yam xeb ntawm cov xov xwm. Nws yog cov hlau sib xyaw uas tsis yooj yim rau xeb, tab sis nws tsis yog xeb kiag li.
