ASTM B443 yog ib qho tseem ceeb vim tias nws tswj hwm cov khoom pov thawj muaj zog thiab corrosion tsis zoo rau cov ntaub ntawv xws li kev ua yeeb yam, aerospace, thiab marine Industries.
2. Dab tsi ua rau Inconel 625 (ASTM B443) corrosion {{}} tiv taus?
Teb:
Inconel 625 (Alloy 625) muaj npe rau nws cov kev ua kom zoo dua vim nws cov cim muaj pes tsawg leeg, uas suav nrog:
Nickel (58%): Muab kev ua tau zoo tshaj plaws rau oxidation thiab corrosion thiab corrosion ntawm qhov kub.
Chromium (20 {{{- 23%): txhim kho oxidation tsis kam, tshwj xeeb hauv cov acidic thiab qhov chaw kub.
Molybdenum (8-10%): Muab kev tiv thaiv kom pitting thiab crevice corrosion, tshwj xeeb tshaj yog hauv kev txo ib puag ncig.
Niobium (3.15-4.15%): Ua rau pom qhov tsis kam ua rau muaj kev txhim kho nruab nrab thiab txhim kho kom muaj zog kub.
Kev sib xyaw ua ke ntawm cov ntsiab no tsim ib qho alloy uas tiv thaiv ib puag ncig ntawm dej hiav txwv, oxidizing kev daws teeb meem, accidizing thiab siab {}} kub oxidation.
3. Dab tsi yog cov ntawv teev cov ntawv teev tseg ntawm Inconel 625 Phaj (ASTM B443)?
Teb:
Inconel 625 Phaj, vim nws lub zog siab, oxidation tsis kam, thiab corrosion tsis kam, yog dav siv nyob rau hauv ntau qhov kev lag luam, suav nrog:
Aerospace: rau cov hniav lim dej, cov ntsaws ruaj ruaj, thiab kev thawb tshuab vim nws lub peev xwm los tiv thaiv ntau qhov kub.
Tshuaj lom neeg: hauv reactors, kev sib pauv cua kub, thiab cov raj xa pa hluav taws xob, qhov twg nws yog nthuav tawm cov tshuaj muaj kuab, acids, thiab kub.
Marine Engineering: In seawater applications like boat hulls, propeller shafts, and underwater components because it resists chloride-induced stress corrosion cracking.
Lub zog nuclear: siv nyob rau hauv reactor cores, piping, thiab cua sov sib pauv uas muaj kev tiv thaiv hluav taws kub thiab corrosion tsis kam.
Roj & Roj: Rau cov cuab yeej siv tau zoo li thaj chaw hnyav thiab thaj av ua kom sib sib zog nqus, raws li nws tuaj yeem tiv taus ntau yam thiab cov tshuaj corrosive.
4. Dab tsi yog qhov ntsuas kub uas tsis txawv ntawm 625 (ASTM B443) tuaj yeem tiv taus?
Teb:
Inconel 625 retains nws lub zog thiab corrosion tsis kam ntawm ntau kub heev. Nws yog feem ntau siv nyob rau hauv kub los ntawm:
Txog li 982℃(1800℃f) hauv kev pabcuam txuas ntxiv.
Txog li 1093℃(2000℃f) hauv kev pabcuam sib quas ntus.
Nws cov kev tiv thaiv zoo heev rau oxidation thiab scaling ntawm qhov kub ua rau siv rau hauv cov ntawv thov, xws li cov cua sov, cov pa roj av, thiab cov tshuab kaw.
5.. Ua li cas Inconel 625 piv rau lwm qhov corrosion-} resistant alloys zoo li Incoloy 825 lossis Hastelloy?
Teb:
Thaum Incoloy 825 thiab Hastelloy yog ob qho tib si tiv taus corrosion, inconel 625 (ASTM B443) muaj qhov zoo tshwj xeeb:
Inconel 625:
Qhov zoo tshaj plaws rau high - sov daim ntawv thov nrog rau oxidation thiab corrosion thiab corrosion thiab corrosion thiab corrosion thiab corrosion nyob rau hauv ib cheeb tsam zoo li kev nqus tshuab, kev hloov pauv cua sov, thiab reactors tshav kub kub.
Muaj qhov siab tshaj plaws tsis kam mus pitting, corrosion corrosion, thiab chloride kev ntxhov siab corrosion tawg ntawm cov alloys.
Ua tau zoo nyob rau hauv huab heev aerospace thiab tubrog nkoj.
Incoloy 825:
Tshaj tawm ntau ntxiv rau cov sulfuric acid, phosphoric acid, thiab lwm cov tshuaj muaj lus tshwj xeeb piv rau inconel 625.
Nws feem ntau siv rau hauv kev ua yeeb yam thiab acidic ib puag ncig, thaum inconel 625 yog qhov zoo dua rau kev kub siab dua, oxidatative ib puag ncig.
Hastelloy (xws li haastelloy C-276):
Superior nyob rau hauv ib puag ncig uas muaj zog reducing acids (zoo li hydrochloric acid) yog tam sim no.
Hastelloy yog feem ntau nyiam rau cov ntawv thov ua haujlwm uas xav tau kev zam tshwj xeeb rau ntau yam tshuaj lom neeg, suav nrog cov muaj zog acids thiab chlorides.
Zuag qhia tag nrho, Inconel 625 feem ntau xaiv rau cov ntawv thov uas muaj kev cuam tshuam nrog kev ua kom haum rau cov neeg mob corrosive, tshwj xeeb tshaj yog hauv kev ua kom muaj tshuaj lom neeg.
