3. Dab tsi yog qhov muaj pes tsawg leeg ntawm hastelloy C-276?
Teb:
Qhov muaj pes tsawg ntawm Hastelloy C-276 yog tsim los muab cov tshuaj corrosion tsis kam thiab muaj zog hauv ib puag ncig uas nyuaj:
Nickel (kwv yees li . 55-60%)
Chromium (14.5-16.5%)
Molybdenum (15-17%)
Hlau (Tshuav)
Cov nyiaj me me ntawm Tungsten, Carbon, silicon, manganese, thiab cobalt txhawm rau txhim kho kev ua tau zoo hauv cov chaw muaj kev nyab xeeb.
Qhov no muaj kev sib xyaw no muab hastellloy C-276 nws cov kev tiv thaiv zoo tshaj plaws rau pitting, kev nyuaj siab corrosion tawg, thiab oxidation ntawm ntug ntsuas kub.
4. Dab tsi yog cov cuab yeej siv tshuab ntawm hastelloy C-276?
Teb:
Hastelloy C-276 muaj kev sib xyaw ua ke, ductility, thiab corrosion tsis kam:
Lub zog tensile: kwv yees li 860 mpa (125,000 PSI) ntawm chav tsev kub.
Tos lub zog: ncig ntawm 345 MPa (50,000 PSI), uas muab nws muaj zog tiv taus deformation nyob rau hauv load.
Elongation: 40-50%, muab kev tsim kom zoo ua kom zoo thiab duction txawm tias nyob rau ntawm ntug kev kub siab.
Hardness: Feem ntau ntawm 85-95 hrb, uas qhia tau zoo tsis kam hnav thiab kev yaig.
Cov khoom siv no, ua ke nrog nws cov siab corrosion tsis kam, ua kom haastelloy C-276 zoo tagnrho rau kev siv cov ntawv thov tau.
5. Dab tsi yog qhov zoo ntawm kev siv hastelloy c-276 yeeb nkab tshaj lwm cov ntaub ntawv?
Teb:
Hastelloy C-276 muaj ntau qhov zoo dua lwm cov ntaub ntawv hauv cov ntawv thov kev lag luam tseem ceeb:
Zoo heev corrosion: nws zoo nyob hauv ib puag ncig uas lwm cov alloys, suav nrog cov hlau stainless thiab titanium, tsis tuaj yeem tiv thaiv. Nws tiv cov tshuaj, suav nrog cov neeg hauv acidic, alkaline, thiab chloride-nplua nuj ib puag ncig.
Kev ua kub kub: nws tuaj yeem tiv taus kub txog 1100℃(2000℃f) yam tsis poob nws lub zog lossis oxidation thiab scaling.
Siv sijhawm ntev dua: Vim nws muaj peev xwm tiv thaiv corrosion thiab kev cuam tshuam, haastelloy C-276 muaj kev pab ntau dua li lwm cov ntaub ntawv, txo tus nqi kho thiab downtime.
Cov ntawv thov ntau ntau: Nws tuaj yeem siv rau ntau qhov kev lag luam, los ntawm kev ua lag luam rau cov neeg siv tshuaj, ua rau nws muaj ntau yam.
Weldability: nws yog weldable heev, uas ua rau nws haum rau kev txhim kho nyuaj thiab kev kho vaj tse hauv lub tshav pob.
Cov txiaj ntsig no ua Hastelloy C-276 ib qho ntawm cov feem ntau txhim khu kev qha thiab ruaj khov rau kev lag luam uas muaj kev ua tau zoo thiab kub yog qhov tseem ceeb.
