This invention relates to the field of chain manufacturing, specifically to a heat treatment method for flat wire materials used in chains. Addressing the problems of existing processes such as sensitivity to the surface activity of incoming materials, abrupt changes in the diffusion gradient, excessive decarburization and deformation, and insufficient batch consistency, a synergistic path of "manganese phosphating—pre-oxidation—segmented carbon potential carburizing—oil quenching—low-temperature tempering" is proposed. First, a controllable manganese phosphating film is constructed on the surface of the flat wire material, and a stable precursor phase is formed through pre-oxidation. Then, during the carburizing stage, it is transformed in situ into a nano-micro composite interface, which, in conjunction with segmented carbon potential, achieves a gradual adjustment of carbon flux from rapid to stable. Finally, appropriate quenching and tempering releases the phase transformation stress. This method obtains flat wire materials with a smooth microstructure gradient, stable surface, and controlled dimensional changes without requiring additional thermal cycles. It significantly reduces decarburization and deformation, improves the wear resistance and early elongation performance of the mating components, and enhances batch consistency.
