Incoloy 825 (UNS8825 / W.NR.2.4858) is an iron-nickel-chromium alloy with additions of molybdenum, copper and titanium. The chemical composition of the alloy is designed for operating conditions requiring excellent resistance to various corrosive environments. The nickel content of the composition is sufficient to provide corrosion cracking resistance to chloride ions. The combination of nickel with molybdenum and copper is also remarkably resistant to reducing environments such as sulfuric and phosphoric acids. At the same time, the molybdenum contributes to the improvement of resistance to pitting and tower corrosion. The chromium in the alloy is resistant to various oxidizing substances, such as nitric acid, nitrates and oxidizing salts. After proper heat treatment, the addition of titanium can stabilize the alloy structure, thereby avoiding intergranular corrosion sensitization. Therefore, Incoloy 825 alloy has good corrosion resistance cracking performance, support corrosion resistance and pitting corrosion resistance, oxidation resistance and hot acid reduction performance. heating pipes, etc.
Incoloy 825 alloy is an austenitic nickel-iron-chromium alloy stabilized by titanium. It has high hardness and strength in high temperature environment. By adding alloying elements such as molybdenum and copper, it can be used for more difficult to bear stainless steel Complex and harsh corrosive environment. When the alloy composition is constant, the corrosion resistance and mechanical properties of the alloy mainly depend on its microstructure, composition and distribution of precipitated phases, etc., and different heat treatment processes have great influence on the microstructure, grain size, and composition of precipitated phases of the alloy. , distribution, quantity and size, etc. will have a greater impact.
The nickel-based superalloy Incoloy 825 is resistant to acid and alkali metal corrosion under both oxidizing and reducing conditions, because the high nickel content makes the alloy have good stress corrosion resistance. Under strong acid conditions such as sulfuric acid, hydrochloric acid and nitric acid, strong alkali solutions such as sodium hydroxide and potassium hydroxide, and mixed solutions of nitric acid, hydrochloric acid and copper sulfate, etc., all show good comprehensive performance. Inco825 nickel base alloy can be used as a heat and corrosion resistant material as effectively as alloy 650. Excellent high temperature strength, strong acid corrosion resistance, oxidation resistance and carburization ability make this alloy widely used in various industrial and chemical equipment, which usually work in extremely harsh high temperature environment.
The nickel-based superalloy Inco825 is difficult to smelt, especially the molten metal is viscous and easy to block. The titanium and copper in the composition are elements that are easy to absorb oxygen. Through many research and development experiments, we have successfully used our patented technology supersonic speed The laminar flow atomization powder making technology has realized the mass production of Inco825 high temperature nickel-based alloy powder.
Incoloy 825 superalloy powder produced by our company is a common process in daily applications: high-speed laser cladding, which provides surface treatment for workpieces, can significantly improve the corrosion resistance and heat resistance of workpieces in high-temperature environments, and is relatively common. There are significant applications in the valve industry and the oil pipeline industry.
