NO8825 is a high alloy corrosion-resistant and high-temperature stainless steel material， also known as Inconel 825. It is mainly composed of elements such as nickel， chromium， copper， and molybdenum， and has characteristics such as high strength， high corrosion resistance， and high temperature performance.
NO8825 is widely used in heating pipes， containers， baskets， and chains used in sulfuric acid pickling plants. Seawater cooling heat exchanger， marine product pipeline system， acidic gas environment pipeline. Heat exchangers， evaporators， washing， impregnation tubes， etc. in the production of phosphoric acid. Air heat exchangers in petroleum refining， food engineering， chemical processes.
Incoloy825 Advantages:
- Strong corrosion resistance: NO8825 has good corrosion resistance in various corrosive media such as acid， alkaline， seawater， and sulfuric acid.
- Good high-temperature performance: NO8825 can operate stably in high-temperature environments.
- Good weldability: NO8825 has excellent weldability and can be used for various processing methods.
Incoloy825 Characteristics:
- Good stress corrosion cracking resistance
- Good resistance to spot corrosion and crevice corrosion
- Excellent antioxidant and non oxidative thermal acid properties
- Excellent mechanical properties at room temperature and high temperatures up to 550 ℃
- Certification for pressure vessels with manufacturing temperatures up to 450 ℃
