Dab tsi yog qhov txawv ntawm 430 thiab 439 stainless hlau?

Stainless hlau yog cov khoom siv alloy dav siv hauv lub neej niaj hnub thiab kev tsim khoom, thiab tau txais kev pom zoo rau nws zoo heev corrosion kuj thiab lub zog. Ntawm ntau hom stainless hlau, 430 thiab 439 yog ob hom, tab sis muaj qee qhov sib txawv tseem ceeb ntawm lawv.

Los ntawm cov tshuaj muaj pes tsawg leeg taw tes ntawm view

430 stainless hlau yog cov hlau alloy uas muaj 16-18% chromium thiab tsis muaj npib tsib xee. Qhov no muab nws zoo heev corrosion kuj nyob rau hauv qee qhov chaw, tshwj xeeb tshaj yog nyob rau hauv oxidizing media. 439 stainless hlau yog cov hlau alloy uas muaj 17-19% chromium thiab 2-3% npib tsib xee. Qhov sib ntxiv ntawm nickel tsis tsuas yog txhim kho corrosion kuj ntawm cov khoom, tab sis kuj txhim kho nws cov toughness thiab processability.

Hais txog lub cev muaj zog

430 stainless hlau yog martensitic stainless hlau nrog siab hardness thiab lub zog, tab sis kuj tsis tshua muaj ductility thiab toughness. Qhov no ua rau nws tsim nyog rau qee yam kev siv uas yuav tsum muaj zog dua. 439 stainless hlau yog ib hom austenitic stainless hlau, nrog zoo ductility thiab toughness, muaj peev xwm tiv taus loj deformation thiab tsis yooj yim rau tawg.

Tsis tas li ntawd, muaj qhov sib txawv ntawm ob qho tib si hauv daim ntawv thov. Vim muaj corrosion kuj thiab siab zog ntawm 430 stainless hlau, nws yog feem ntau siv nyob rau hauv lub tsim ntawm automotive tso systems, ntxhua khaub ncaws, chav ua noj thiab lwm yam khoom uas yuav tsum tau tiv taus kub thiab corrosive ib puag ncig. 439 stainless hlau yog dav siv hauv petrochemical, khoom siv kho mob, ua zaub mov thiab lwm yam kev lag luam vim nws cov khoom ua haujlwm zoo thiab kev tiv thaiv corrosion.

Hauv cov ntsiab lus, 430 thiab 439 stainless hlau muaj qee qhov sib txawv hauv cov tshuaj muaj pes tsawg leeg, cov khoom siv lub cev thiab daim ntawv thov. Kev nkag siab txog qhov sib txawv no pab peb xaiv kom zoo dua thiab siv cov ntaub ntawv stainless hlau kom tau raws li qhov xav tau ntawm ntau qhov chaw thiab kev siv.
