Alloy825 UNS N08825 saumattomat putket

Alloy 825 (UNS N08825) is an austenitic nickel-iron-chromium alloy with additions of molybdenum, copper andtitanium.html> titanium. It was developed to provide excellent corrosion resistance in oxidizing and reducing environments. The alloy is resistant to chloride stress corrosion cracking and pitting. The addition of titanium makes the N08825 alloy non-sensitizing in the welded state and makes the alloy resistant to intergranular corrosion after exposure to a temperature range that would sensitize unstable stainless steels. The manufacture of N08825 alloy is typical of nickel-based alloys, and the material is easily formed and welded by various techniques.
Application fields of UNS N08825:
condenser
Oil and gas well equipment
Hydraulic system
chemical injection line
Chemical Process Equipment and Vessels
Downhole control pipeline
Controls and Instrumentation
acid production

nuclear fuel processing

Alloy825|UNS N08825 is a NI-FE-MO-CU corrosion-resistant alloy stabilized with Ti. The alloy has effective resistance to uniform corrosion and localized corrosion, and has good performance. Therefore, it is used in chemistry, energy, and hydrometallurgy. Widely used. In addition, the alloy has good toughness and is also good in the atmosphere, but it should be noted that shallow pitting will occur in the humid atmosphere. This alloy is also resistant to corrosion in fresh water, and it is good in all conditions in flowing seawater. , but in still seawater or polluted conditions will produce spots.

Alloy825|UNS N08825 high nickel content makes the alloy have effective resistance to stress corrosion cracking. Corrosion resistance in various media is very good, such as sulfuric acid, phosphoric acid, nitric acid and organic acids, alkali metals such as sodium hydroxide, potassium hydroxide and hydrochloric acid solution. The high comprehensive performance of Alloy825|UNS N08825 is manifested in nuclear combustion dissolvers with various corrosive media, such as sulfuric acid, nitric acid and sodium hydroxide, which are all processed in the same equipment.

Alloy825|UNS N08825 material characteristics:

●Good resistance to stress corrosion cracking.

●Good resistance to pitting corrosion and crevice corrosion

●Excellent oxidation resistance and non-oxidative thermal acid performance

●Excellent mechanical properties at room temperature and high temperature up to 550°C
