GH4169 high temperature alloy wire mesh characteristics, grades, characteristics, technical standards
GH4169 high temperature alloy wire mesh is known as GH4169 high temperature alloy wire woven mesh, GH4169 high temperature alloy wire filter mesh, GH4169 high temperature alloy wire screen, GH4169 high temperature alloy wire square hole mesh.
GH4169 alloy has good comprehensive performance in the temperature range of -253 ~ 700 ℃, and the yield strength below 650 ℃ ranks first among deformed high temperature alloys. It also has good fatigue resistance, radiation resistance, oxidation resistance, corrosion resistance, as well as good processing performance and welding performance. It can manufacture various parts with complex shapes and has been widely used in aerospace, nuclear energy, petroleum industry and extrusion dies within the above temperature range.
Another feature of GH4169 high temperature alloy wire mesh is that the alloy structure is particularly sensitive to hot working technology. By mastering the laws of phase precipitation and dissolution in the alloy and the relationship between the structure and process and performance, reasonable and feasible process specifications can be formulated for different use requirements, and various parts that meet different strength levels and use requirements can be obtained. The varieties supplied include forgings, forged bars, rolled bars, cold rolled bars, round cakes, rings, plates, strips, wires, tubes, etc. They can be made into discs, rings, blades, shafts, fasteners and elastic elements, plate structural parts, casings and other parts for long-term use in aviation.

The chemical composition of GH4169 high temperature alloy wire mesh is divided into 3 categories: standard composition, high quality composition, and high purity composition, as shown in Table 1-1. The high quality composition reduces carbon and increases niobium on the basis of the standard composition, thereby reducing the amount of niobium carbide, reducing the number of fatigue sources and strengthening phases, increasing the fatigue resistance content, and improving the purity and comprehensive performance of the material. The
GH4169 alloy used in nuclear energy applications needs to control the boron content (other element components remain unchanged), and the specific content is determined by negotiation between the two parties in the process. When ω (B) ≤ 0.002%, in order to distinguish it from the GH4169 alloy used in the aerospace industry, the alloy grade is GH4169A.
