ХН60ВМТЮР - ЭИ618 sheet, round, wire
High-temperature Nickel-based alloy ХН60ВМТЮР (or ХН60МВТЮ, ЭП487-VD, ХН60МВТЮ-VD, ЭП487) used in the aircraft industry for the production of fasteners and rails, and gas turbine blades. The recommended maximum operating temperature for a limited period of time — 750 — 800 °C. Temperature in air intensive scaling equal to 1000−1050 °C. the Material in modern engines, turbine blades must have a high resistance to destruction by heat, low cycle fatigue, which today is the main form of destruction. To worsen the danger of destruction capable of surface reactions due to the weakening of grain boundaries and gas corrosion. The main requirements to the material for the manufacture of turbine blades are subject to the latest developments of the designs of engines, a continuous increase in ductility, resistance to low cycle, thermal fatigue, heat resistance and resistance to gas environments.
