Heat-resistant steel tray castings: key materials in the aerospace and new energy fields

Heat-resistant steel tray castings play an increasingly important role in the aerospace and new energy fields due to their excellent high-temperature performance and corrosion resistance. The following are their applications and developments in two major fields:

1. Applications in the aerospace field
In the aerospace field, heat-resistant steel tray castings are widely used in engine components, high-temperature structural parts, and aerospace equipment. These components need to maintain stable performance and reliability under high temperature, high pressure and high stress environments. For example, ZG40Cr25Ni20Si2 heat-resistant steel casting plates are used in key components of aerospace engines due to their excellent high-temperature strength and corrosion resistance. In addition, austenitic heat-resistant steel has also become an ideal material for high-temperature engine components and advanced gas turbines in the aerospace field due to its high-temperature strength and corrosion resistance.

2. Applications in the new energy field
With the rapid development of new energy technologies, the application of heat-resistant steel tray castings in the field of renewable energy is also expanding. For example, in high-temperature gas-cooled reactors and solar thermal power generation systems, heat-resistant steel castings can withstand extreme high temperature environments to ensure the stable operation of the system. In addition, heat-resistant steel castings are also used in key components of new energy vehicles to meet their performance requirements in high temperature environments.

3. Technological progress and industry dynamics
In recent years, heat-resistant steel castings have made significant progress in material science and casting technology. By optimizing alloy composition design and improving heat treatment processes, the high temperature resistance and service life of heat-resistant steel castings have been significantly improved. At the same time, with the development of precision casting technology, the application of heat-resistant steel tray castings in the manufacture of precision components and tiny parts has gradually increased.
