Thaum tshav kub kub-resistant stainless hlau yeeb nkab yog ib tug high-alloy stainless hlau yeeb nkab belongs rau 25Cr-20Ni series. Nws muaj qhov kub thiab txias oxidation kuj zoo heev thiab tsim nyog rau qhov kub-tiv taus hauv qab 1200 degree. cov
Kub-resistant stainless hlau yeeb nkab nta
1) Kub kub oxidation kuj zoo heev;
2) Kev khiav hauj lwm kub ntau yog dav heev (hauv qab 1200 degree);
3) Tsis-sib nqus nyob rau hauv cov ntsiab lus daws teeb meem;
4) Lub zog kub kub. cov
Kub-resistant stainless hlau yeeb nkab thov ntau yam
Cov kav dej tso pa tawm, cov kav dej, cov kav dej kho cua sov, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob thiab lwm yam hlau uas yuav tsum tau ua kom muaj cua sov, kub kub / kub tiv taus qhov chaw
Thaum tshav kub kub-resistant stainless hlau yeeb nkab yog austenitic chromium-nickel stainless hlau nrog zoo oxidation kuj thiab corrosion kuj. Vim tias qhov feem pua ntawm cov chromium thiab npib tsib xee ntau dua, nws muaj zog nkag tau zoo dua, tuaj yeem ua haujlwm txuas ntxiv ntawm qhov kub thiab txias, thiab muaj qhov kub zoo. Vim nws cov ntsiab lus siab ntawm nickel (Ni) thiab chromium (Cr), nws muaj oxidation zoo thiab corrosion kuj. Acid, alkali thiab kub tsis kam, cov kav dej kub-resistant steel yog tshwj xeeb yog siv rau kev tsim hluav taws xob rauv taws thiab lwm yam sijhawm. Tom qab nce cov ntsiab lus carbon hauv austenitic stainless hlau, lub zog yog txhim kho vim nws cov khoom muaj zog ntxiv zog. Chemistry ntawm austenitic stainless hlau Cov yam ntxwv muaj pes tsawg leeg yog raws li chromium thiab npib tsib xee nrog cov ntsiab lus xws li molybdenum, tungsten, niobium thiab titanium ntxiv. Txij li thaum nws cov qauv yog lub ntsej muag-centered cubic qauv, nws muaj lub zog siab thiab creep lub zog ntawm qhov kub thiab txias.
