Aviation forgings refer to metal parts used in the aviation field to withstand mechanical loads under high strength and high temperature environments, usually made of steel materials. Aviation forgings have the characteristics of high strength, high toughness and excellent fatigue resistance, which can maintain stable performance under harsh working conditions. The selection of iron and steel materials for aviation forgings mainly considers the following factors: strength and rigidity: in a high strength and high temperature environment, aviation forgings need to have sufficient strength and rigidity to resist the mechanical load imposed on them. Therefore, it is very important to choose steel materials with high strength and good rigidity. Resistance to high temperature oxidation: In a high temperature environment, the forgings in the aircraft engine will be exposed to high temperature airflow and combustion products, and it is necessary to have a certain resistance to high temperature oxidation. Therefore, iron and steel materials need to have excellent high-temperature oxidation resistance to ensure the long-term reliable operation of aviation forgings. Fatigue life: Aviation forgings are usually subjected to complex and frequent loads, so they need to have a good fatigue life. High strength steel materials can provide a long fatigue life, thereby extending the service life of aviation forgings. Metallurgical properties: The metallurgical properties of iron and steel materials have an important impact on the manufacturing of aviation forgings. Good metallurgical properties can ensure the uniformity, toughness and plasticity of the material, and improve the machining performance and stability of aviation forgings. In general, the steel body of aviation forgings needs to choose iron and steel materials with high strength, good resistance to high temperature oxidation, long fatigue life and good metallurgical properties. Such materials can ensure that aviation forgings have excellent mechanical properties and reliability in high strength and high temperature environments, and become a sharp tool to cope with high strength and high temperature conditions.
