ASTM A790 UNS S31803 Yeeb Nkab

ASTM A790 UNS S31803 yog ib qho kev qhia tshwj xeeb hauv cov khoom siv hlau duplex. Cov khoom siv yog cov hlau alloy nrog chromium thiab molybdenum hauv nws. Qhov sib ntxiv ntawm cov ntaub ntawv no ua rau cov kav dej muaj zog thiab tiv taus corrosion ntau. SA 790 UNS S31803 yog ib qho ntawm cov qib super duplex uas muaj zog dua thiab tiv taus corrosion.

Khoom Taw qhia

Duplex Steel UNS S31803Cov kav dej muaj ob qho tib si ferritic thiab austenitic alloy cov khoom, uas yog superior nyob rau hauv tag nrho cov kev ua tau zoo rau cov stainless hlau kav xws li 316 thiab 316L, thiab yog txhim khu kev qha nyob rau hauv kuj rau ntau yam corrosion. Cov kav dej no tau tsim tshwj xeeb rau cov hom phiaj thiab cov ntawv thov uas yuav tsum muaj kev tiv thaiv corrosion. Qib ntawm cov yeeb nkab no yog machinable heev nyob rau hauv ib puag ncig hnyav thiab kuj ua tau zoo nyob rau hauv aqueous ib puag ncig. Tag nrho cov Duplex UNS S31803 stainless hlau kav yog cov cua sov kho ntawm qhov ntsuas kub thiab qhov kub thiab txias. Txawm hais tias cov tshuaj muaj pes tsawg leeg ntawm qib ntawm cov yeeb nkab no zoo ib yam li lwm cov qib austenitic ntawm stainless hlau yeeb nkab.

UNS S31803 Duplex Stainless Hlau Yeeb Nkab Corrosion Resistance

Qib 2205 stainless hlau nthuav tawm zoo heev corrosion kuj, ntau dua li ntawm qib 316. Nws tiv taus cov kab mob hauv zos xws li intergranular, crevice thiab pitting. CPT ntawm no hom stainless hlau yog nyob ib ncig ntawm 35 degree. Cov qib no tiv taus chloride kev nyuaj siab corrosion tawg (SCC) ntawm qhov kub ntawm 150 degree. Qib 2205 stainless hlau yog qhov hloov tau zoo rau qib austenitic, tshwj xeeb tshaj yog nyob rau hauv qhov chaw ua tsis tiav ntxov thiab ib puag ncig marine.

UNS S31803 Duplex Steel Yeeb Nkab Thaum tshav kub kub kuj

Lub siab oxidation kuj cuab yeej ntawm Qib 2205 yog marred los ntawm nws embrittlement saum 300 degree. Qhov embrittlement no tuaj yeem hloov kho los ntawm kev daws teeb meem annealing tag nrho. Qib no ua tau zoo ntawm qhov kub qis dua 300 degree.
