Processing method of 25-6HN
Processing method of 25-6HN
The processing methods of 25-6HN alloy include but are not limited to cold forming, hot rolling, heat treatment, and mechanical processing using special cutting tools and equipment.
Cold forming: 25-6HN can be processed by any conventional cold forming method, such as bending, stretching, etc. Since 25-6HN has a higher elastic limit, greater force may be required to perform operations, and intermediate annealing may be required to restore the material's softness after severe shaping.
Hot rolling: It is one of the commonly used hot processing methods of Incoloy 25-6HN. In the hot rolling process, the material is heated to high temperatures and then pressed through rollers to achieve the desired thickness and size. In order to improve the surface quality, hydrogen protected hot rolling technology can be used to reduce oxidation and contamination.
Heat treatment: Heat treatment is an important step for Incoloy 25-6HN, which can optimize its properties through solution treatment and aging treatment. Solid solution treatment can promote the uniform distribution of alloy elements, while aging treatment can improve the strength and corrosion resistance of the alloy by promoting the precipitation of certain elements to form a strengthening phase.
Machining: Due to the high strength and hardness of 25-6HN, special cutting tools and equipment are required to avoid damaging the surface and edges of the material. At the same time, it is necessary to adopt appropriate cutting parameters and use appropriate cutting fluid to ensure processing efficiency and product quality.
In summary, Incoloy 25-6HN is a high-strength, corrosion-resistant alloy with excellent high-temperature properties and hot-corrosion resistance. Therefore, when selecting a processing method, these characteristics need to be taken into consideration and corresponding measures must be taken to ensure processing quality and efficiency.
