The sprocket is crafted using specialized materials developed in collaboration with professional institutions and incorporates multiple advanced manufacturing processes: The grain structure is refined and impurities are reduced through electroslag remelting; its strength and toughness are elevated to over 1,300 MPa via press forging; and processing precision exceeding IT6 grade is achieved through a fully automated digital production line. Paired with digital tempering-quenching and contour-controlled heat treatment featuring full parameter traceability, it achieves a balanced performance of "ductile matrix and wear-resistant working surfaces." Subsequent high-precision chain pocket quenching ensures a hardness of ≥HRC55 and a quenched layer depth of ≥15 mm. The product demonstrates efficient synergy with chains, significantly enhancing its wear resistance and fatigue resistance.
