A358 Qib 347H EFW Pipes

A358 TP347 hluav taws xob fusion welded yeeb nkab yog austenitic acid-resistant stainless hlau yeeb nkab uas ua tau zoo nyob rau hauv corrosive ib puag ncig uas muaj acids, alkalis, thiab ntsev. Nws yog tsim rau siv nyob rau hauv kev lag luam xws li aviation, roj av, tshuaj, thiab zaub mov. Nyob rau hauv cov huab cua ntawm qhov kub ntawm 750-800 degree, A358 TP347 steel yeeb nkab muaj qhov ruaj khov oxidation tsis kam. TP347 steel yog austenitic tshav kub-resistant stainless hlau, belongs rau 18-8 hom chromium-nickel austenitic stainless hlau, sib npaug rau Tuam Tshoj tus 1Cr19Ni11Nb. Austenitic heat-resistant stainless hlau yog tsim los ntawm Fe-Cr-Ni ternary equilibrium daim duab qhia tau hais tias thaum cov ntsiab lus Cr ntau dua los yog sib npaug rau 18% thiab Ni cov ntsiab lus ntau dua los yog sib npaug rau 8%, ib qho. -phase austenite tuaj yeem tau txais ntawm chav tsev kub. Hauv Suav teb, qhov no yog hu ua 18-8 steel. Vim tias cov hlau no muaj ib theem austenitic qauv, nws tsis zoo li tawv tom qab vuam. Txawm li cas los xij, thaum lub sij hawm vuam, nws yooj yim rau intergranular corrosion, kev nyuaj siab corrosion cracking, thiab vuam kub tawg.
