65Mn material is a type of spring steel with a higher carbon content, giving it higher hardness and strength. It is commonly used for manufacturing products that require high elasticity and wear resistance, such as springs and blades. In contrast, wheel steel is a specialized alloy steel used for manufacturing wheels. It typically possesses good toughness and impact resistance to ensure the safety and durability of wheel forgings during high-speed rotation and heavy loads.

The main differences between the two lie in their chemical composition, mechanical properties, and application areas. Additionally, 65Mn material, after heat treatment, exhibits good hardenability and temper stability, making it easy to process and shape, though its corrosion resistance is relatively weak.

Wheel steel, on the other hand, can be categorized into various types depending on its intended use and manufacturing standards, such as high-strength wheel steel and corrosion-resistant wheel steel. These different types of wheel steel vary in chemical composition and microstructure to meet specific manufacturing requirements.

In terms of manufacturing processes, 65Mn material is typically processed into the desired shape through hot rolling, cold rolling, and forging, followed by quenching and tempering to enhance its mechanical properties. Wheel steel is generally produced using continuous casting, hot rolling, and cold rolling to achieve good microstructure and mechanical performance.

In summary, 65Mn material and wheel steel differ significantly in terms of chemical composition, mechanical properties, application areas, and forging processes. Therefore, when selecting materials, it is important to make a reasonable choice based on specific usage requirements and working environments.
