Super Nickel Based Alloy Sheet Corrosion Resistance Incoloy 825 UNS N08825 Nickel Alloy Plate
INCOLOY 825:
Incoloy 825 is a high-performance nickel-iron-chromium alloy. Its chemical composition includes nickel (38-46%), chromium (19.5-23.5%), iron (balance), carbon (≤0.025%), manganese (≤1.0 %), silicon (≤0.5%), copper (1.5-3.0%), molybdenum (2.5-3.5%), aluminum (≤0.2%), titanium (0.6-1.2%) and other elements. The physical properties of this alloy include a density of 8.14 g/cm³ and a melting point of 1370-1400°C. At normal temperature, its minimum mechanical properties include tensile strength 550 N/mm², yield strength 220 N/mm², elongation 30% and Brinell hardness ≤ 200.
The properties of Incoloy 825 include good resistance to stress corrosion cracking, pitting and crevice corrosion, resistance to oxidizing and non-oxidizing hot acids, and good mechanical properties at room temperature and at elevated temperatures up to 550°C. In addition, the alloy has certification for manufacturing pressure vessels up to 450°C.
Incoloy 825 is widely used in various industrial fields where the operating temperature does not exceed 550°C, such as heating tubes, containers, baskets and chains used in sulfuric acid pickling plants, seawater cooling heat exchangers, marine product pipeline systems, acid gas environment pipelines, Heat exchangers, evaporators, washers, dip tubes, etc. in phosphoric acid production, air heat exchangers in petroleum refining, food engineering, chemical processes, and flame retardant alloys for pressurized oxygen applications.
Incoloy 825 is suitable for welding with the same material or other metals using any traditional welding process, such as tungsten electrode inert gas shielded welding, plasma arc welding, manual sub-arc welding, metal electrode inert gas shielded welding, and melting electrode inert gas shielded welding. When using manual arc welding, it is recommended to use a shielding gas mixed with (Ar+He+H2+CO2) multiple components. Welding must be carried out in the annealed state, and stains, dust and various marks must be cleaned with a stainless steel wire brush.
