Qhov sib txawv ntawm 904L stainless hlau kauj thiab SS304 stainless hlau kauj feem ntau nyob hauv cov hauv qab no:
1. Tshuaj muaj pes tsawg leeg: 904L stainless hlau muaj ntau cov nickel, chromium, thiab molybdenum, thaum SS304 stainless hlau muaj tsawg ntawm cov ntsiab lus. 904L stainless hlau kuj tseem muaj cov ntsiab lus tooj liab ntau dua.
2. Corrosion resistance: Vim nws cov ntsiab lus siab ntawm nickel, chromium, thiab molybdenum, 904L stainless hlau muaj zog corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv sulfuric acid, hydrochloric acid, thiab lwm yam muaj zog acid ib puag ncig. SS304 stainless hlau muaj qhov zoo corrosion kuj nyob rau hauv ib puag ncig corrosive.
3. Lub zog thiab hardness: 904L stainless hlau muaj zog dua thiab hardness dua SS304 stainless hlau.
4. Machinability: Vim nws lub zog siab thiab hardness, 904L stainless hlau muaj kev ua haujlwm tsis zoo, thaum SS304 stainless hlau yog qhov yooj yim rau txheej txheem.
5. Nqe: Vim yog cov ntsiab lus siab dua ntawm cov hlau tseem ceeb hauv 904L stainless hlau, nws cov nqi feem ntau yog siab dua li ntawm SS304 stainless hlau.
Nyob rau hauv cov ntsiab lus, 904L stainless hlau kauj muaj zoo corrosion kuj thiab txhua yam khoom dua li SS304 stainless hlau kauj, tab sis nws yog kim dua. Qhov kev xaiv ntawm cov khoom yog nyob ntawm qhov kev thov tshwj xeeb thiab kev xav txog nyiaj txiag.
