Nws yog dav siv nyob rau hauv gas turbines, muaj cua sov tshuab, thiab incineration systems.
Inconel 750 (ASTM UNS N07750) yog npib tsib xee-chromium alloy feem ntau yog siv rau hauv siab- kev ntxhov siab, siab- kub daim ntawv thov xws li turbine hniav, lub tshuab tso pa, thiab combustion chambers. Nws muaj kev nkag siab zoo heev thiab feem ntau yog siv hauv aerospace thiab fais fab kev lag luam.
Thaum ob qho tib si alloys yog siv nyob rau hauv siab - qhov kub thiab txias ib puag ncig, Inconel 601 feem ntau yog siv rau oxidation tsis kam, thaum Inconel 750 yog ntau tsom rau siab - lub zog thiab creep kuj ntawm siab kub.
4. Vim li cas Hastelloy B2 thiab Inconel 825 nyiam nyob rau hauv ib puag ncig corrosive heev?
Teb:
Hastelloy B2 (ASTM UNS N10665) yog npib tsib xee- molybdenum alloy tshwj xeeb tsim los siv rau hauv ib puag ncig corrosive heev xws li hydrochloric acid thiab tshuaj ua haujlwm. Nws muaj kev tiv thaiv zoo heev rau ob qho tib si txo thiab oxidizing ib puag ncig thiab tshwj xeeb tshaj yog zoo nyob rau hauv ib puag ncig nrog cov kua qaub siab thiab siab - qhov kub thiab txias.
Inconel 825 (ASTM UNS N08825) yog npib tsib xee -chromium- hlau alloy nrog ntxiv molybdenum thiab tooj liab, ua rau nws tiv taus corrosion, kev nyuaj siab- corrosion cracking, thiab oxidation. Nws yog siv nyob rau hauv daim ntawv thov xws li tshuaj ua, nuclear roj reprocessing, thiab flue gas desulfurization vim nws zoo heev tsis kam mus sulfuric acid, phosphoric acid, thiab chlorides.
Ob qho khoom siv raug xaiv rau qhov chaw muaj corrosive heev vim tias lawv muab cov tshuaj tiv thaiv zoo rau cov tshuaj lom neeg, ua kom muaj zog hauv kev lag luam xws li kev tsim tshuaj lom neeg thiab kev ua lag luam petrochemical.
5. Dab tsi yog daim ntawv thov ntawm Nickel Steel Yeeb Nkab / Tubes ua los ntawm Inconel, Hastelloy, thiab Monel?
