Cov ntsiab lus kom zoo dua ntawm cov kav hlau stainless nyob hauv nws cov cim npe sib xyaw tag nrho. Los ntawm kev ntxiv cov ntsiab xws li chromium (CR), npib tsib), thiab molybdenum zaj duab xis (passivation zaj duab xis (passivation zaj duab xis), ua rau zoo heev corrosion. Raws li nws microstructure, stainless hlau tuaj yeem faib ua cov hauv qab no:
Austenitic Stainless Hlau (304 thiab 316 series): Muaj 18% -20% Nickel, nws muaj cov khoom noj zoo heev, thiab yog cov khoom siv tshuaj ntsuab, thiab khoom ua vajtse. Piv txwv li, 304 stainless hlau yog siv rau hauv chav ua noj ua noj, thaum 316 stainless hlau (nrog ntxiv molybdenum) yog siv hauv cov nkoj marine lossis cov khoom siv kho mob.
Ferritic steel hlau (430 Series): Muaj 12% -18% Kev Tawm Tsam Yog Tsis Zoo rau Austenitic Stainless Hlau, tab sis nws tsis tshua kim. Nws yog ib qho muaj nyob rau hauv cov cuab yeej cuab yeej cuab tam, kev ua twj tso tsheb hlau, thiab lwm yam kev siv.
Martensitic Stainless Hlau (420 Series): muaj 12% -14% chromium, nws tuaj yeem tsim tau riam, thiab lwm yam kev siv.
Duplex Stainless Hlau (2205, 2507 Series): sib txuas ua ke thiab feem ntau siv hauv petrochemical, marine engineering thiab lwm thaj teb.
