Khoom Taw qhia

Nickel alloy 725 /ib 725yog nickel chromium-molybdenum-niobium alloy uas muaj zog tiv taus corrosion thiab muaj hnub nyoog hardenable rau lub zog siab heev. Nws muaj qhov tseem ceeb tib yam corrosion kuj zoo li INCONEL alloy 625, uas yog dav siv nyob rau hauv ib tug ntau yam ntawm corrosive ib puag ncig. Lub zog ntawm lub hnub nyoog-hardened Alloy 725 yog ntawm qhov kev txiav txim ntawm ob zaug ntawm annealed alloy 625.

Mechanical Properties

Inconel alloy 617 muaj cov khoom siv kho tshuab siab tshaj qhov kub thiab txias. Ib qho ntawm cov yam ntxwv zoo tshaj plaws ntawm cov alloy yog lub zog theem nws tswj ntawm qhov kub thiab txias. Qhov kev tiv thaiv ntawm cov alloy rau high-temperature corrosion txhim khu kev pab ntawm nws lub zog.

Corrosion Resistance

Cov muaj pes tsawg leeg ntawm Inconel alloy 617 suav nrog ntau cov nyiaj npib tsib xee, chromium, thiab txhuas rau qib siab ntawm kev tiv thaiv oxidation thiab carburization ntawm qhov kub thiab txias. Cov ntsiab lus no, nrog rau cov ntsiab lus molybdenum, kuj ua rau cov hlau tiv taus ntau qhov chaw ntub dej corrosive.
