| It is a NI-FE-MO-CU corrosion-resistant alloy stabilized with Ti, which has effective resistance to uniform corrosion and local corrosion, and has good performance. Therefore, it is widely used in chemistry, energy, and hydrometallurgy. In addition, the alloy has good toughness, and it also works well in the atmosphere. However, it should be noted that shallow pitting corrosion can occur in humid atmospheres. This alloy is also resistant to freshwater corrosion, and has good performance in various applications in flowing seawater, However, in still seawater or under polluted conditions, point like structures can occur. The high nickel content of Incoloy825 makes the alloy have effective resistance to stress corrosion cracking. Good corrosion resistance in various media, as well as alkali metals such as sodium hydroxide, potassium hydroxide, The high comprehensive performance of Incoloy 825 is demonstrated in the nuclear combustion dissolver with diverse corrosive media, all treated in the same equipment. | |||||||||||||||
