300 series stainless hlau yog cov hlau stainless hlau alloys uas nws lub ntsiab feature yog cov ntsiab lus siab ntawm nickel thiab chromium. Qhov no series ntawm stainless hlau feem ntau suav nrog 304 stainless hlau, 316 stainless hlau thiab lwm yam qauv. Piv nrog 200 series stainless hlau, 300 series stainless hlau muaj cov yam ntxwv hauv qab no:
1. Kev tiv thaiv corrosion zoo heev: Cov ntsiab lus siab nickel thiab chromium endows 300 series stainless hlau nrog zoo corrosion kuj, ua rau nws ua tau zoo nyob rau hauv ntau yam corrosive media thiab hnyav ib puag ncig. Tshwj xeeb tshaj yog haum rau seawater, tshuaj, acidic thiab alkaline ib puag ncig.
2. Lub zog siab dua: 300 series stainless hlau feem ntau muaj lub zog siab dua 200 series stainless hlau, muab cov qauv kev ruaj khov thiab tensile zog ntau dua.
3. Zoo plasticity thiab machinability: 300 series stainless hlau muaj cov yas zoo thiab tuaj yeem siv rau hauv kev tsim thiab molding ntawm ntau yam duab. Nyob rau tib lub sijhawm, nws cov machinability kuj zoo heev, uas yooj yim rau kev txiav, vuam thiab ua haujlwm txias.
4. Daim ntawv thov dav: 300 series stainless hlau yog dav siv hauv kev lag luam chemical, marine, khoom noj khoom haus, khoom siv kho mob, shipbuilding, architectural kho kom zoo nkauj thiab lwm yam kev lag luam, nrog rau ntau yam kev lag luam kev siv uas yuav tsum tau muaj corrosion kuj.
5. Kev kub siab ua haujlwm: Qee qhov 300 series stainless hlau (xws li 316 stainless hlau) kuj muaj qhov kub thiab txias tsis kam thiab tsim nyog siv rau hauv qhov kub thiab txias.
Txawm hais tias 300 series stainless hlau muaj zoo heev corrosion kuj thiab siab zog, nws kuj yog kim piv rau 200 series stainless hlau.
Kev faib tawm
300 series stainless hlau tuaj yeem muab faib ua ntau hom kev faib tawm raws li nws qhov tshwj xeeb muaj pes tsawg leeg thiab cov yam ntxwv:
1. 304 stainless hlau (UNS S30400): 304 stainless hlau yog feem ntau 300 series stainless hlau, muaj li ntawm 18 feem pua chromium thiab 8 feem pua nickel. Nws muaj kev tiv thaiv corrosion zoo heev, zoo txhua yam khoom thiab kev kho cua sov, thiab tsim nyog rau ntau yam kev siv xws li khoom noj khoom haus, ntim tshuaj, kho kom zoo nkauj, thiab lwm yam.
2. 316 stainless hlau (UNS S31600): 316 stainless hlau yog qib high-qib corrosion-resistant stainless hlau, muaj li ntawm 16 feem pua chromium thiab 10 feem pua nickel, thiab 2 feem pua molybdenum ntxiv. Nws ua tau zoo nyob rau hauv ib puag ncig corrosive thiab tshwj xeeb tshaj yog tsim rau cov dej hiav txwv ib puag ncig, cov cuab yeej siv tshuaj lom neeg, khoom siv kho mob, thiab lwm yam.
3. 310 stainless hlau (UNS S31000): 310 stainless hlau muaj li 25 feem pua chromium thiab 20 feem pua nickel. Nws lub ntsiab feature yog kub tsis kam thiab yog haum rau siv nyob rau hauv high kub ib puag ncig, xws li qhov cub thiab cov khoom siv kho cua sov.
4. 321 stainless hlau (UNS S32100): 321 stainless hlau muaj li ntawm 18 feem pua chromium thiab 9 feem pua nickel, thiab titanium ntxiv. Nws muaj kev tiv thaiv corrosion zoo heev thiab kub tsis kam, thiab tsim nyog rau qhov kub thiab txias ib puag ncig thiab lub sijhawm uas muaj kev tiv thaiv corrosion siab.
5. 347 stainless hlau (UNS S34700): 347 stainless hlau muaj li ntawm 18 feem pua chromium thiab 11 feem pua nickel, thiab molybdenum thiab niobium ntxiv. Nws muaj kev tiv thaiv corrosion zoo heev thiab kub tsis kam, thiab tshwj xeeb tshaj yog haum rau lub sijhawm muaj kev tiv thaiv corrosion siab hauv qhov kub thiab txias.
Ntxiv nrog rau cov lus hais saum toj no, 300 series stainless hlau kuj suav nrog qee yam tshwj xeeb, txhua hom muaj cov tshuaj sib txawv thiab cov khoom siv kho tshuab, thiab tsim nyog rau kev thov tshwj xeeb.
