INCOLOY 825 nickel-raws li alloy, ib qho kev xaiv rau stainless hlau
INCOLOY 825 Description
INCOLOY alloy 825 yog nickel-hlau-chromium alloy nrog ntxiv ntawm molybdenum, tooj liab, thiab titanium. Lub alloy cov tshuaj muaj pes tsawg leeg, muab nyob rau hauv Table 1, yog tsim los muab tshwj xeeb kuj rau ntau corrosive ib puag ncig. Cov ntsiab lus npib tsib xee txaus rau kev tiv thaiv chloride-ion kev ntxhov siab-corrosion tawg. 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 acids. Cov molybdenum kuj pab tiv thaiv pitting thiab crevice corrosion. Lub alloy cov ntsiab lus chromium confers tsis kam mus rau ntau yam oxidizing tshuaj xws li nitric acid, nitrates thiab oxidizing ntsev. Qhov sib ntxiv ntawm titanium ua haujlwm, nrog rau kev kho cua sov kom tsim nyog, kom ruaj khov ntawm cov hlau tiv thaiv rhiab heev rau intergranular corrosion. Qhov tsis kam ntawm INCOLOY alloy 825 rau kev dav dav thiab hauv cheeb tsam corrosion nyob rau hauv ntau yam xwm txheej muab cov alloy dav dav. Cov ntawv thov suav nrog kev ua tshuaj lom neeg, tswj kev ua qias tuaj, roj thiab roj rov qab, kev tsim cov kua qaub, kev ua haujlwm pickling, nuclear roj reprocessing, thiab tuav cov khoom siv hluav taws xob. Daim ntawv thov rau alloy 825 zoo ib yam li cov INCOLOY alloy 020.
Yog vim li cas INCOLOY 825 hloov stainless hlau
Nickel-iron-chromium alloys, such as Alloy 825, also known as Incoloy 825 (Specialty Metals' line of nickel-iron-chromium alloys is called Incoloy), are designed to provide more cost-effective solutions for applications requiring high temperatures and corrosion resistance - By lowering the nickel content (with more exotic alloys). Duplex stainless steel and super duplex stainless steel are quite "real" in terms of corrosion resistance and strength. However, there are certain deficiencies within the operating temperature range in which INCOLOY 825 works. The yield strength of standard super duplex alloys is greater than 80ksi, while the yield strength of INCOLOY 825 is only greater than 36ksi. Likewise, PREN (pitting resistance equivalent number) is only 31, while super duplex alloys reach >40. tab sis: a) Alloy 825 tuaj yeem siv rau ntawm kev ua haujlwm kub txog 540 degree, thaum super duplex stainless hlau muaj qhov kub thiab txias ntawm 250 degree. b) INCOLOY 825 khaws cia feem ntau ntawm nws cov kev cuam tshuam lub zog ntawm qhov kub tsis tshua muaj zog, whereas cov khoom ntawm duplex thiab superduplex stainless hlau zoo li degrade ntawm qhov kub thiab txias heev.The siab nickel ntsiab lus ntawm INCOLOY 825 xyuas kom tsis txhob muaj kev ntxhov siab corrosion cracking. Qhov sib ntxiv ntawm molybdenum thiab tooj liab ua rau nws tiv thaiv kom tsis txhob muaj ib puag ncig xws li liuic acid thiab phosphoric acid. Kev tswj qhov sib ntxiv ntawm titanium tuaj yeem cuam tshuam intergranular corrosion uas yuav tshwm sim ntawm qhov kub thiab txias.
Cov yam ntxwv ntawm Incoloy 825 yog
• Ua tau zoo heev los txo thiab oxidizing acids
• Zoo tiv thaiv kev ntxhov siab corrosion tawg
• Txaus siab rau kev tawm tsam hauv zos xws li pitting thiab crevice corrosion
• tiv taus acid thiab phosphoric acid heev
• Cov khoom siv kho tshuab zoo ntawm chav tsev thiab qhov kub siab txog li 1000 degree F
• Tso cai siv cov hlab ntsha siab nrog phab ntsa kub txog 800 degree F
