Dab tsi yog 300 series stainless hlau?

300 series stainless hlau tau dav siv hauv liaj teb xws li kev tsim kho, kev tsim khoom siv, thiab ua zaub mov noj. Nws cov neeg sawv cev raug suav nrog cov qauv xws li 304 thiab 316, uas yog feem ntau muaj zog los ntawm kev ua kom txias dua li kev kho cua sov

Dab tsi yog cov qauv thiab cov xwm txheej thov?
304 Stainless Hlau: feem ntau hom, muaj 18% npib chromium thiab 8% npib tsib xee, siv rau cov khoom siv hauv tsev, khoom siv tsev, thiab lwm yam.
316 Stainless hlau: Ntxiv Molybdenum caij kom txhim kho corrosion tsis kam, haum rau cov khoom siv hnyav xws li cov khoom siv dej hiav txwv thiab cov tshuaj chemical. ‌‌
321 Stainless Hlau: Muaj cov titanium kom tiv thaiv intergranular corrosion, feem ntau siv nyob rau hauv qhov chaw siab (xws li lub dav hlau tso dej rau cov kav dej)

Dab tsi yog qhov sib txawv ntawm SS316 thiab SS302?

SS316 tau txhim kho nws txoj kev txhim kho corrosion thiab kub tsis kam lees txog Molybdenum (MO), xws li nyob rau hauv chloride (xws li sillwater) thiab muaj zog acid) thiab muaj zog acid) thiab muaj zog acid) thiab muaj zog acid) thiab muaj zog acid) thiab muaj zog acid) thiab muaj zog acid) thiab muaj zog acid) thiab muaj zog acid) thiab muaj zog acid) thiab muaj zog acid) thiab muaj zog acid) thiab muaj zog acid
SS302 muaj cov ntsiab lus tsib xee tsawg dua thiab cov ntsiab lus muaj roj carbon ntau dua, muaj zog dua tab sis tsis muaj zog corrosion tsis kam.

 

Puas yog 300 lossis 400 stainless hlau zoo dua?

300 series stainless hlau ua tau zoo dua nyob rau hauv feem ntau thov cov xwm txheej. 300 series stainless hlau muaj zoo corrosion tsis kam, muaj cov khoom siv tshuaj, ua kom cov khoom siv kho mob, thiab cov khoom siv kho mob uas yuav tsum muaj cov khoom siv kho mob thiab corrosion resistance. Txawm hais tias 400 series stainless hlau muaj tus nqi qis dua thiab siab dua rau cov cuab yeej tsim khoom xws li cov cuab yeej tsim, thiab bearings uas yuav tsum muaj hardness thiab hnav tsis kam

 

Dab tsi yog qhov zoo ntawm 300 series stainless hlau?

Corrosion Kuj: 300 series stainless hlau muaj qhov siab ntawm Nickel lub caij, uas tuaj yeem tsim cov yeeb yaj kiab ruaj khov rau ntawm cov khoom siv, tiv thaiv kev xeb
Formancion: Nws muaj cov qauv zoo, yog ib qho yooj yim rau cov txheej txheem rau hauv ntau yam duab, thiab yog qhov tsim nyog rau kev tsim cov qauv kev ua haujlwm
Weldability: Zoo Weldability zoo, yooj yim rau Weld, haum rau cov ntawv thov kev lag luam uas yuav tsum tau ua kom haum vuam
