Incoloy 926 nta:
1. Nws muaj lub tswb nrov sib txawv corrosion kuj thiab tuaj yeem siv rau hauv nruab nrab uas muaj cov kua qaub.
2. Nws tau raug pov thawj nyob rau hauv kev xyaum hais tias nws yog zoo nyob rau hauv resisting chloride kev nyuaj siab corrosion cracking.
3. Txhua yam corrosive ib puag ncig muaj corrosion kuj zoo.
4. Cov khoom siv ntawm Alloy 904 L tau zoo dua li cov Alloy 904 L.
