Incoloy 825 phaj yog dab tsi?
Incoloy 825 alloy phaj hauv UNS N08825 / ASTM B424. Muaj kub- dov thiab txias- dov, thickness 0.3-1200mm. Corrosion-resistant nyob rau hauv acids, chlorides & H₂S. Thov ib tsab ntawv hnub no.
Alloy 825 Phaj yog ua los ntawm Nickel- hlau-chromium alloy nrog ntxiv ntawm molybdenum, tooj liab, thiab titanium. Incoloy 825 Plate cov tshuaj muaj pes tsawg leeg muab tshwj xeeb tsis kam rau ntau qhov chaw corrosive. Cov ntsiab lus Nickel ntawm Alloy 825 Nickel Sheet txaus rau kev tiv thaiv Chloride-ion kev nyuaj siab corrosion cracking. Cov npib tsib xee, ua ke nrog molybdenum thiab tooj liab, kuj tseem ua rau muaj kev tiv thaiv zoo rau kev txo qis ib puag ncig xws li cov uas muaj sulfuric thiab phosphoric acid. Lub molybdenum ntawm UNS N08825 Phaj kuj pab tiv thaiv pitting thiab crevice corrosion. Lub alloy Chromium cov ntsiab lus confers tsis kam mus rau ntau yam oxidizing tshuaj xws li nitric acid, nitrates, thiab oxidizing ntsev. Qhov sib ntxiv ntawm titanium, nrog rau kev kho cua sov kom tsim nyog, yuav ruaj khov ntawm cov hlau tiv thaiv rhiab heev rau intergranular corrosion.

FAQ:
Q: Qhov txawv ntawm Incoloy 825 thiab Incoloy 825HT yog dab tsi?
- A: 825HT yog qhov txawv ntawm 825; nws nta cov ntsiab lus titanium hloov kho uas txhim kho nws qhov siab -kub creep zog. 825 yog tsim rau corrosion- daim ntaub ntawv tiv taus ntawm kub hauv qab 450℃; Txawm li cas los xij, yog tias kev ua haujlwm siab tshaj qhov ntsuas kub no, nws raug nquahu kom xav txog 825HT.
Q: Ob leeg ASTM B424 thiab B163 npog alloy 825; Qhov txawv ntawm lawv yog dab tsi?
- A: B424 yog tus qauv rau cov khoom siv phaj thiab ntawv. B163 npog seamless raj, B704 npog welded raj, thiab B366 npog cov yeeb nkab fittings. Thaum ua kev yuav khoom, nws yog ib qho tseem ceeb kom meej meej qhia meej txog cov khoom tsim nyog.
Q: Thaum xaiv cov ntaub ntawv ntub dej - txheej txheem phosphoric acid cov cuab yeej, puas yog 825 tsim nyog, lossis nws puas tsim nyog hloov kho rau C-276?
- A: Wet-process phosphoric acid environments involve a complex corrosive mix of fluorides (HF), chloride ions, and low pH levels. The combination of copper and molybdenum in 825 provides adequate corrosion resistance across most concentration ranges. However, if the phosphoric acid concentration is exceptionally high (>85%) lossis qhov kub siab tshaj 80 degree, nws raug nquahu kom ntsuas kev siv C-276.
Q: Thaum siv 825 phaj khoom rau FGD nqus tsev, yuav ua li cas xaiv thickness?
- A: Cov kab hlau txuas rau FGD yees feem ntau muaj 3-8 hli txias- cov ntawv dov. Qhov tshwj xeeb thickness yuav tsum yog nyob ntawm tej yam xws li kev tsim siab, kev tiv thaiv corrosion, thiab cov qauv kev txhawb nqa. Rau qhov chaw tiav, ib qho 2B lossis BA tiav yog feem ntau xaiv.
Q: Dab tsi yog qhov sib txawv ntawm chloride -ion corrosion kuj ntawm 825 thiab 316L?
- A: Qhov txawv yog qhov tseem ceeb. Qhov Critical Pitting Temperature (CPT) rau 316L ntog nyob rau hauv 15-25℃ntau yam, txhais tau hais tias txawm tias qhov kub nce me ntsis hauv dej hiav txwv tuaj yeem ua rau pitting corrosion. Hauv qhov sib piv, CPT rau 825 tshaj 40 degree; ua ke nrog nws cov ntsiab lus 38% npib tsib xee, ob lub alloys tsuas yog nyob hauv cov pab pawg sib txawv.
Q: Yog tias ob qho tib si 825 thiab 625 tsim nyog rau daim ntawv thov, tus nqi sib txawv ntawm lawv yog dab tsi?
- A: 625 nta cov ntsiab lus nickel pib ntawm 58% thiab cov ntsiab lus molybdenum ncav cuag siab li 8-10%; Tsis tas li ntawd, nws muaj zog los ntawm kev suav nrog niobium. Yog li ntawd, nws tus nqi feem ntau yog 40-60% siab dua li ntawm 825.
