Peb feem ntau xaiv yam twgtxoj hlua barbedes tsis txhob ntawm txoj hlua barbed.Qhov tseeb, hom hlua khi yog qhov tseem ceeb raws li hom hlua khi.Cia peb tham txog qhov sib txawv ntawm 304 thiab 201 ntawm barbed hlau dov tawb.
Qhov sib txawv ntawm 304 thiab 201 stainless hlau hlau dov tawb yog qhov sib txawv ntawm cov khoom, cov khoom txiav txim siab tus nqi, yog li tus nqi ntawm 304 stainless hlau hniav gill net yog me ntsis siab dua, cov hauv qab no feem ntau piav qhia qhov txawv ntawm ob cov ntaub ntawv raw.
Ua ntej, feem ntau siv stainless hlau phaj yog muab faib ua ob hom 201 thiab 304, qhov tseeb muaj pes tsawg leeg ntawm Nestor tawb txawv, 304 stainless hlau Nestor tawb zoo dua, tab sis tus nqi yog kim, 201 yog qhov phem dua.Anping 304 rau imported stainless hlau phaj, Anping 201 rau domestic stainless hlau phaj.
Thib ob, muaj pes tsawg leeg.Qauv 201 yog tsim los ntawm 17Cr-4.5Ni-6Mn-N, uas yog hloov cov hlau rau hom 301 steel.Anping hlau dov tawb yog sib nqus tom qab ua haujlwm txias, siv hauv tsheb ciav hlau.304 muaj pes tsawg leeg ntawm 18Cr-9Ni, yog cov feem ntau siv stainless hlau, kub resistant hlau.Siv rau cov khoom siv khoom noj khoom haus, Xitong chemical khoom, nuclear zog, thiab lwm yam.
Peb, 201 yog siab manganese cov ntsiab lus, qhov saum npoo yog ci heev nrog tsaus ci, cov ntsiab lus siab manganese yog yooj yim rau xeb.304 muaj ntau chromium, nto yog matte, tsis muaj xeb.Muab ob qho tib si ua ke thiab koj muaj kev sib piv.Qhov tseem ceeb tshaj plaws yog qhov kev tiv thaiv corrosion txawv.Kev tiv thaiv corrosion ntawm 201 yog qhov tsis zoo, yog li tus nqi yuav pheej yig dua.Vim tias cov ntsiab lus tsis tshua muaj npib tsib xee ntawm 201, tus nqi qis dua 304, yog li qhov corrosion kuj tsis zoo li 304.
Plaub, qhov sib txawv ntawm 201 thiab 304 yog qhov teeb meem ntawm nickel.Thiab tus nqi ntawm 304 kuj tseem kim tam sim no, feem ntau ze rau 20,000 yuan ib tuj, tab sis 304 tsawg kawg tuaj yeem ua kom ntseeg tau tias nws yuav tsis xeb hauv cov txheej txheem siv.(Kev sim nrog potions)
Thib tsib, stainless hlau tsis yooj yim rau xeb vim tias kev tsim cov nplua nuj chromium oxide nyob rau saum npoo ntawm lub cev steel tuaj yeem tiv thaiv lub cev steel, 201 cov khoom belongs rau siab manganese stainless hlau tshaj 304 hardness ntawm high carbon tsawg nickel.
Thib rau, sib txawv muaj pes tsawg leeg (tsuas yog los ntawm carbon, manganese, npib tsib xee, chromium kom paub qhov txawv 201 thiab 304 stainless hlau) steel carbon (C) silicon (Si) manganese (Mn) phosphorus (P) sulfur (S) chromium (Cr) nickel (Ni ) molybdenum (Mo) tooj liab (Cu) 304 stainless hlau yog ib yam khoom siv thoob ntiaj teb stainless hlau, xeb kuj muaj zog tshaj 200 series stainless hlau cov ntaub ntawv, 600 degrees kub kuj.Nws muaj zoo heev stainless corrosion kuj thiab zoo intergranular corrosion kuj.Nws kuj muaj qhov zoo corrosion kuj rau alkali tov thiab feem ntau cov organic acids thiab inorganic acids.
