KHN55VMTKJU, ЭИ929 round, wire, tube, sheet, strip
Material marked KHN55VMTKJU belongs to the category of high-temperature materials, as they are able to withstand during operation a very considerable temperature loads. This quality is due to the content material of Nickel, which determines its main characteristics and operational parameters. Additional alloying of some other chemical elements greatly improves performance of raw materials and expanding its original scope. To date, these alloys are very widely used in many areas of production and constantly replenished with new improved brands.
the basic qualities
Since the main application of such materials is the manufacture of parts of aircraft and gas turbine engines, the material properties must meet the highest performance requirements of this sector. In addition to high heat resistance (temperature of the working area of the part can reach nine hundred and fifty degrees) alloy KHN55VMTKJU perfectly resists corrosion gas type. This type of corrosion damage is the greatest danger to elements of the turbine, as it provokes the intensification of the processes of weakening on the grain boundaries, the phase structure of the material. In addition, the raw material of this type is quite flexible, which facilitates its handling in the manufacturing process of semi-finished products. However, when applying it is worth considering that in order to prevent the active formation of scale on the surface of the product, its operating temperature should not exceed 1050 degrees Celsius.
