Gnee tub team
S34700 steel yeeb nkabyog ib qho austenitic stainless hlau nrog zoo heev corrosion kuj thiab kub lub zog vim qhov sib ntxiv ntawm lub ntiaj teb tsis tshua muaj caij neodymium thiab alloying ntsiab xws li titanium thiab niobium. Nws yog dav siv hauv tshuaj, roj av, tshuaj thiab zaub mov.
Cov tshuaj muaj pes tsawg leeg ntawm S34700 stainless hlau yeeb nkab: S34700 yog tsim los ntawm hlau, chromium, npib tsib xee, titanium, neodymium, niobium thiab lwm yam khoom. Cov tshuaj muaj pes tsawg leeg tshwj xeeb yog: hlau (Fe) Ntau dua lossis sib npaug rau 68.00%, chromium (Cr) Ntau dua lossis sib npaug rau 17.00%, npib tsib xee (Ni) Ntau dua lossis sib npaug rau 9.00%, titanium (Ti) Ntau dua lossis sib npaug li 5 × C-0.45%, neodymium (Nd) Tsawg dua lossis sib npaug li 0.15%, niobium (Nb) Tsawg dua los yog sib npaug li 1.00%, thiab lwm yam.
347 stainless hlau yeeb nkab muaj lub zog tensile siab thiab yield zog. Lub zog tensile ntau dua los yog sib npaug rau 520 MPa thiab lub zog tawm los yog ntau dua lossis sib npaug rau 205 MPa. Tsis tas li ntawd, nws hardness tsawg dua los yog sib npaug rau 187HBW.
S34700 stainless hlau tuab-walled yeeb nkab muaj corrosion kuj zoo thiab tshwj xeeb tshaj yog haum rau kev ua hauj lwm kub thiab acidic ib puag ncig. Nws tiv taus sulfuric acid, nitric acid, hydrofluoric acid thiab chloride ions.
