Nickel alloys alloyed with certain other chemical elements to enhance their original properties and ensure high material stability have become a solid foundation for the development of most modern industrial industries. After all, good heat resistance, resistance to corrosion damage, a high temperature index that determines the beginning of scale formation on the surface of the product against a background of considerable plasticity allows such raw materials to work effectively in the most difficult production conditions.
characteristic
The alloy ХН62МВКЮ can successfully perform its basic functions when exposed to sufficiently high temperatures in the working area (up to nine hundred degrees), without reducing its operational parameters. The high content of nickel in the material promotes the formation on its surface of a strong film coating, which protects the main body of the part from damage to corrosion properties. It is especially important to note the presence in such raw materials of good resistance to fatigue processes caused by high-temperature exposure and inertness in relation to the aggressive influence of the gaseous medium. Such unique properties of products from this alloy have found their main application in the field of manufacturing various turbine-type engines.
