Txog 07Cr19NI11Ti Steel Yeeb Nkab
1. Dab tsi yog 07cr19NI11ti?
07cr19Ni11Ti yog Austenitic stainless hlau, tshav kub {{ove {{{} {resantant alloy steel. Nws muaj pes tsawg leeg muaj kwv yees li ntawm 19% chromium (CR) thiab 11% tsib xee (ni). Titanium (ti) ntxiv ua cov khoom ruaj khov kom tiv thaiv kev txhim kho hauv nruab nrab. Cov qib zoo sib xws suav nrog tus qauv GB hauv tsev neeg 0cr18ni10ti (qib qub) thiab International Astm txheem 321 stainless hlau.
2. Dab tsi yog cov yam ntxwv tseem ceeb ntawm cov yeeb nkab steel no?
Siab - kub kuj: nws tuaj yeem siv rau lub sijhawm ntev ntawm 700 {} 800 {200}
Corrosion Kuj: nws tiv thaiv oxidation thiab acid thiab alkali corrosion, thiab yog tshwj xeeb yog tsim nyog rau ib puag ncig muaj chloride muaj cov nqaij ntses (xws li seasater) lossis cov kua qaub tsis muaj zog.
Cov txheej txheem: qhov sib ntxiv ntawm titanium (ti) txhim kho weldability thiab txo cov rhiab vim los ntawm carbide nag lossis daus tom qab vuam.
3. Dab tsi yog cov chaw thov tseem ceeb? Petrochemical Kev Lag Luam: Cov kav dej chemical, reactors, thiab kev hloov cua sov.
Khoom noj khoom haus thiab kev lag luam khoom noj khoom haus: cov khoom siv tsis muaj zog thiab cov khoom siv corrosion {{free {tiv taus kav dej.
Kev kho tsheb / Kev Lag Luam Aviation: Tso Kav thiab Turnacine Cheebtsam.
Kev lag luam hluav taws xob nuclear hluav taws xob: qee qhov hluav taws xob - tsis kam ntawm qhov chaw (raug rau cov pov thawj ntxiv).
4. Dab tsi yog qhov txawv ntawm 304 thiab 316 Stainless hlau?
304 (06cr19NI10): muaj tsis muaj Titanium, ua pov thawj tsis muaj zog intergranular tsis kam, thiab tsis muaj siab}}} kub ua piv rau 321.
316 (06Cr17NI12MI2NI2NKI2NI): muaj molybdenum (mo), muaj txhim kho chloside ion corrosion, tab sis tsis muaj siab}} kub stability piv rau 321.
07cr19Ni11ti: Titanium ruaj khov, ua rau muaj kev ruaj khov ntau dua tom qab vuam thiab haum rau he- kub welded Cheebtsam.
5. Cov teeb meem twg kuv yuav tsum txiav txim siab thaum yuav khoom?
Muaj cov qauv: xws li GB / T 14976 (cov roj tsheb thauj khoom) thiab ASTM A312 (txheej txheem thoob ntiaj teb).
Kev kuaj cov ntsiab lus: Cov ntsiab lus titanium yuav tsum muaj ntau dua los yog sib npaug rau 5 × C% (Cov ntsiab lus carbon) kom ntseeg tau tias muaj kev tsim tawm kom ntseeg tau. Kev kho deg: pickling (ap) lossis ci annaling (ba), nyob ntawm lub corrosion tiv thaiv.
