NCF825 superalloy is a corrosion-resistant and heat-resistant alloy, which is widely used in chemical, energy and hydrometallurgical fields. The alloy has good resistance to uniform corrosion and local corrosion, and has good toughness, resistance to atmospheric and fresh water corrosion. However, pitting corrosion can occur in still seawater or in contaminated conditions. The chemical composition of NCF825 superalloy includes elements such as C, SI, MN, P, S, CR, NI, Cu, Al and Ti. Grades of this alloy include NS1402, NCF825, Incoloy 825, UNS NO8825, etc.
NCF825 is a superalloy that is also known as Incoloy 825. During heat treatment, the properties of the material may change. The following are some of the material properties of NCF825 superalloy during heat treatment:
1.Solid solubility: NCF825 superalloy is solution treated during heat treatment, and the improvement of solid solubility can improve the plasticity and machinability of the alloy.
2.Grain size: Heat treatment can affect the grain size of an alloy. Typically, high-temperature treatment promotes the growth of grains and the formation of larger grains. Changes in grain size can have an impact on the mechanical properties and corrosion resistance of materials.
3.Phase composition: Heat treatment can change the phase composition in an alloy. Through solution treatment and aging treatment, the phase composition and phase content in the alloy may change, which will affect the mechanical properties, corrosion resistance and oxidation resistance of the material.
4.Strength and hardness: Heat treatment can affect the strength and hardness of alloys by changing grain size, phase composition, and phase distribution. Typically, solution treatment can improve the strength and hardness of the alloy, while aging treatment can further adjust the mechanical properties of the alloy.
5.Corrosion resistance: NCF825 superalloy has good corrosion resistance, and the heat treatment process may affect its corrosion resistance. A suitable heat treatment regime can improve the corrosion resistance of the alloy and make it perform better in corrosive media.
It should be noted that the specific parameters of the heat treatment process (e.g., temperature, time, etc.) and the choice of heat treatment regime will have an impact on the material properties. Therefore, it is advisable to refer to the heat treatment guidelines provided by the relevant material manufacturer or consult a professional before proceeding with heat treatment to ensure that the heat treatment process and system can meet the requirements of the material.
