Yield strength:
It can reach about 700 MPa to 800 MPa. Yield strength refers to the stress value at which a material begins to deform considerably when it is subjected to a force, and is usually determined in a tensile test of a material. Its yield strength indicates the ability of a material to begin to plastically deform under a given condition. It is important to note that the specific yield strength depends on factors such as the heat treatment state of the material, the manufacturing process, and the stress conditions, so there can be certain differences.
Widely used in the following fields:1It is often used in aero engine parts, such as turbine blades, compressor blades, combustion chamber parts, etc. Its high-temperature strength and oxidation resistance make it an ideal material for high-temperature and high-pressure working environments. 2.It is also widely used in the chemical industry, and can be used to manufacture high-temperature and corrosion-resistant reaction vessels, heat transfer equipment, valves and pipelines and other components, suitable for use in corrosive media and high-temperature conditions. 3.Its excellent performance makes it used in the nuclear energy industry, such as nuclear fuel cladding in nuclear reactors, nuclear fuel delivery systems, etc., and its ability to resist creep and radiation damage makes it an important structural material in nuclear engineering. 4.It is commonly used in the manufacture of high-temperature and high-pressure downhole equipment, pipelines and valves, with hydrogen sulfide corrosion resistance and high-temperature pressure resistance.
