ASTM B444 Alloy 625 (UNS N06625) Seamless U Bend Tube For Heat exchanger
N06625 metallographic structure:
The microstructure of this alloy in the solid solution state is an austenitic matrix with a small amount of TiN, NbC, and M6C phases. After long-term aging at 650~900 ℃, the precipitated phases are γ',δ, M23C6 and M6C.
N06625 Process Performance and Requirements:
1. This alloy has good cold and hot formability, and the heating temperature for forging steel ingots is 1120 ℃.
2. The average grain size of this alloy is closely related to the degree of deformation of the forging and the final forging temperature.
3. The welding performance of the alloy is good, and it can be used for argon arc welding with tungsten electrode or this alloy as an additive in a protective atmosphere, as well as brazing and resistance seam welding.
4. Surface treatment process: To remove the oxide scale on the alloy surface, first alkali wash, and then acid wash in nitric acid, hydrofluoric acid aqueous solution.
5. When the processing amount of alloy is greater than 15% during cold working, annealing treatment shall be carried out after Hot working.
N06625 Application Area:
1.Components of organic chemical processes containing chlorides, especially when using acidic chloride catalysts;
2.Cooking and bleaching tanks used in the pulp and paper industry;
3.The absorption tower, reheater, flue gas inlet baffle, fan (wet), agitator, guide plate, and flue in the flue gas desulfurization system;
4.Used to manufacture equipment and components for sour gas environment;Acetic acid and acetic anhydride reaction generator;Sulfuric acid condenser, etc.
N06625 Welding:
It is recommended to use AWS A5.14 welding wire ERNiCrMo-3 or AWS A5.11 welding rod ENiCrMo-3 for the welding of N06625 alloy
