1. High hardness and wear resistance
9Cr18MoV is a high-carbon chromium stainless steel. After heat treatment, the hardness can reach HRC 58-62, which is suitable for making high-strength and high-wear-resistant tools and parts. In the design of conical twin screws and cylinders, high hardness and wear resistance mean that the screw can better resist the erosion and wear of materials, extend the service life, while maintaining the accuracy and shape stability of the screw.

2. Good corrosion resistance
9Cr18MoV alloy also has good corrosion resistance and can effectively resist oxidation and corrosion under certain environments. This is especially important for conical twin screws and cylinders that need to work in corrosive environments.

3. Excellent machining performance
9Cr18MoV alloy has good formability and weldability, which makes it easy to process into parts of various shapes. In the manufacturing process of conical twin screws and cylinders, this excellent machining performance makes the manufacture of screws more efficient and precise.

4. Adapt to a variety of working environments
The lightweight and high-strength characteristics of 9Cr18MoV alloy enable it to adapt to a variety of working environments. Whether it is high temperature, high pressure or harsh environment such as acid and alkali, 9Cr18MoV alloy can provide reliable support.

5. Improve overall performance stability
Due to the above advantages of 9Cr18MoV alloy, the use of this alloy in the design of conical twin screws and cylinders can significantly improve the overall performance stability. The improvement of the screw's hardness, wear resistance, corrosion resistance and machining performance will make the equipment more stable and reliable during operation, reducing downtime and maintenance costs caused by failures.
