25Cr2MoVA alloy structural steel

25Cr2MoVA Alloy Structural Steel 25Cr2MoVA alloy structural steel is a kind of low alloy high strength structural steel, its carbon content is not high, and it has good alloying performance and good thermal processing performance, which can be hardened and tempered. This kind of steel not only has high strength and hardness, but also has a certain degree of toughness, good fatigue resistance and impact resistance. It also has a certain degree of corrosion resistance and excellent welding performance. It is widely used in all kinds of pivotal structural parts and important structural components.

The chemical composition of 25Cr2MoVA alloy structural steel is as follows: 0.20-0.28% carbon, 0.90-1.20% chromium, 0.10-0.30% manganese, 0.10-0.50% molybdenum and 0.15-0.30% vanadium. The carbon and manganese content is slightly higher than the requirements of some general construction steels. The chromium content can reach 0.90-1.20%, which is a common feature of most quenched and tempered alloy structural steels. The molybdenum content can reach 0.10-0.50%, and the vanadium content can reach 0.15-0.30%, which meas the amount of quenched and tempered alloying elements in 25Cr2MoVA steel is moderate and has good comprehensive performance.

The performance of 25Cr2MoVA alloy structural steel is excellent. Its tensile strength and yield strength are both very high, up to 1000MPa and 860MPa respectively. Its hot strength is also good and its impact performance is excellent. Its hot strength can reach 900-620MPa, and its impact energy can reach 20-50J. In addition, when used as high temperature parts, it can also maintain certain heat resistance and oxidation resistance at high temperatures. At the same time, due to its high strength, it can effectively reduce its own weight, and its welding performance is also good and its requirements for welding current or gas welding are not high.

25Cr2MoVA alloy structural steel can be used for the manufacture of critical and important large workpieces, or for the attachment of important small parts on the working surface. In addition, due to its good comprehensive performance, it is widely used in many important fields, such as the manufacture of aircraft, missile and other parts. It also has wide application in the fields of nuclear energy and various engineering machinery.

25Cr2MoVA alloy structural steel has excellent performance, and its use can bring considerable economic benefits. Therefore, it is now widely used in many production plants and factories and has been successfully applied in various important constructions. In fact, in the field of precision manufacturing, the application of 25Cr2MoVA alloy structural steel is making great progress. At present, many countries are investing a lot of resources in studying the application of 25Cr2MoVA alloy structural steel and are gradually increasing the production capacity of this steel to meet the needs of the times.

25Cr2MoVA alloy structure steel is superior in machinability, weldability and machinability, and is mainly used to manufacture integral parts and components in various structures and local mechanical parts.

25Cr2MoVA alloy structure steel has strong creep resistance and corrosion resistance, high strength, good formability, good plasticity and relatively low price.

25Cr2MoVA alloy structure steel has superior comprehensive mechanical properties, good tempering stability, and can guard against tempering softening. It is mainly used to manufacture forgings with large load and cross-section and has higher requirements. Such as turbine discs and rotors, mechanical spindles, seamless steel tubes, etc.

25Cr2MoVA alloy structure steel is characterized by low alloying, low carbon content, strong iron-boron segregation and low hardenability. It is suitable for the manufacture of parts that require good stress corrosion resistance and complex cross-sections with good molding performance.

25Cr2MoVA alloy structure steel has good welding performance. The welding heat input should be as small as possible to avoid overburning and overheating of the welds and components.
