Inconel 625 vs Incoloy 825 Alloy Phaj: Yuav xaiv li cas
The choice between Inconel 625 and Incoloy 825 sheets depends on the operating temperature, type of corrosion, and budget. Inconel 625 is suitable for extreme high-temperature environments (>540 degree) thiab muaj zog txhua yam zoo heev. Incoloy 825 yog tsim rau cov ntawv thov uas yuav tsum tau them nqi -cov kua qaub, alkali, thiab chloride tsis kam ntawm qhov kub nruab nrab.
Incoloy 825 khoom yog dab tsi?
Incoloy 825 (UNS N08825) yog austenitic npib tsib xee- hlau-chromium superalloy ntxiv nrog molybdenum, tooj liab, thiab titanium. Nws tau txais txiaj ntsig zoo rau nws txoj kev ua haujlwm zoo rau oxidizing thiab txo cov kua qaub, nws tsis kam mus rau chloride kev nyuaj siab corrosion cracking, thiab nws tsis kam rau pitting corrosion.
