Materials and Processes of Clutch Steel Plates
Materials
High-Carbon Steel
Carbon content typically ranges between 0.6% and 1.0%, endowing it with excellent hardness and wear resistance. It can withstand the significant friction and pressure generated during frequent clutch operations, making it one of the common materials for manufacturing MACK clutch steel plates.
Alloy Steel
On the basis of high-carbon steel, alloying elements such as chromium, nickel, and molybdenum are added to improve the steel plate's heat resistance, impact resistance, and oxidation resistance. These elements alter the steel plate's microstructure, forming fine carbides or alloy carbides, thereby further enhancing its hardness and wear resistance.
Manufacturing Processes
Heat Treatment
Typically undergoes heat treatment processes such as quenching and tempering to further improve hardness and toughness, ensuring better adaptation to usage requirements. Quenching imparts high hardness and strength to the steel plate, while tempering relieves quenching stress, enhances the steel plate's toughness, and optimizes its comprehensive mechanical properties.
Surface Treatment
To enhance corrosion resistance and extend the service life of the clutch plates, the steel plate surface may undergo coating treatments (e.g., galvanizing, nickel plating) or processes such as phosphating and blackening. These form a protective film on the surface to prevent rust and corrosion.
