25Cr2Mova is a low-alloy steel containing chromium (Cr), molybdenum (Mo), vanadium (V), alloyed with a small amount of aluminum (Al). Due to its excellent strength, toughness, heat resistance and corrosion resistance, this alloy steel is especially suitable for the manufacture of important mechanical parts and fasteners working under various high temperatures and pressures, such as high-strength bolts, shafts, gears and other structural components that are subjected to high temperature and high pressure.
High temperature intensity: 25Cr2Mova steel provides good high-temperature strength and creep resistance through a reasonable ratio of alloying elements, so that it can still maintain high strength in high-temperature environments.
Good heat and corrosion resistance: The addition of chromium and molybdenum improves the heat resistance and oxidation resistance of the material, while vanadium improves the particle size stability and toughness of the material.
Excellent mechanical properties: It has high yield strength and tensile strength, as well as good toughness and impact absorption capacity.
Solderability: 25Cr2Mova has some weldability, but special heat treatment may be required before and after welding to ensure the performance of the welded part.
Power industry: High-temperature bolts, fasteners, and other components used in power plant boilers that are subjected to high temperatures.
Petrochemical: It is suitable for the manufacture of fasteners and components for high-temperature and high-pressure pipelines and reactors.
Mechanical engineering: Used for high-strength shafts, gears, fasteners and other key mechanical structural components.
Military and aviation: In the field of military equipment and aviation, it is used in the manufacture of structural components that withstand extreme environmental conditions.
Heat treatment: Performance optimization of 25Cr2MOVA typically relies on heat treatment processes, including quenching and tempering, to obtain the desired hardness and mechanical properties.
Welding: Although it has a certain degree of weldability, measures such as preheating and post-heat treatment are required during the welding process to prevent cracks and improve the performance of welded joints.
When designing and using 25Cr2Mova materials, it is necessary to select the appropriate heat treatment and processing process according to the working conditions and performance requirements of the specific application to ensure the performance and reliability of the part.
