High-temperature-resistant steel kav yog high-alloy stainless hlau kav ntawm 25Cr-20Ni series. High-temperature-resistant steel kav muaj oxidation zoo thiab corrosion kuj. Vim tias lawv muaj feem ntau ntawm cov chromium thiab npib tsib xee, lawv muaj zog dua creep. , tuaj yeem ua haujlwm txuas ntxiv ntawm qhov kub thiab txias, nrog rau kev ua haujlwm kub ntawm 1200 degree thiab kev siv tas li ntawm 1150 degree, thiab muaj qhov kub thiab txias tsis kam.
{{0}}Cr25Ni20 yog ib hom ntawm cov hlau tsis muaj steel uas ua raws li Suav GB qauv. 0Cr25Ni20 yog sib npaug rau American 310S stainless hlau yeeb nkab. 310S muaj 25% chromium thiab 20% npib tsib xee. Vim nws cov ntsiab lus siab ntawm nickel (Ni) thiab chromium (Cr), nws muaj kev tiv thaiv corrosion zoo, acid thiab alkali tsis kam, thiab kub tsis kam. Cov kav dej kub resistant steel tshwj xeeb yog siv rau cov khoom siv hluav taws xob, cov nozzles, combustion chambers, thiab lwm yam, thiab carbon ntxiv rau austenitic stainless hlau. Tom qab cov ntsiab lus, lub zog yog txhim kho vim nws cov khoom muaj zog ntxiv zog. Cov tshuaj lom neeg muaj pes tsawg leeg ntawm austenitic stainless hlau yog raws li chromium thiab npib tsib xee nrog cov ntsiab lus xws li molybdenum, tungsten, niobium thiab titanium ntxiv. Txij li nws cov qauv yog lub ntsej muag-centered cubic qauv, yog li muaj lub zog siab thiab creep lub zog ntawm qhov kub thiab txias. cov
Tshuaj muaj pes tsawg leeg ntawm kub resistant steel yeeb nkab (%): Ni nickel: 19.<= 1.50 Mn manganese <= 2.00 C carbon <= 0.08 S sulfur <= 0.030 P phosphorus <= 0.035.
High kub resistant steel yeeb nkab thov ntau yam
High kub resistant steel kav yog tsim rau ua ntau yam kub resistant rauv tubes, burner nplaim nozzles, nplaim nozzles, teb kiln raj, sintering rauv tubes, kub kub rauv tubes, hluav taws xob rauv tubes, iav hlaws sintering rauv tubes, teb kiln Unloading chaw nres nkoj. , 1200 degree siab kub resistant rauv tube, 1300 degree siab kub resistant rauv tube, nruam siv kub 1150 degree. Daim ntawv thov cov khoom lag luam: cov kav dej tso tawm, cov khoom siv hluav taws xob kho cua sov, cov khoom siv hluav taws xob sib txuas, cov tshuab hluav taws xob thiab lwm yam hlau uas yuav tsum tau ua kom muaj cua sov, kub kub / kub tiv taus qhov chaw.
