These standards are filed for management and calibrated periodically. Product sample blocks are stored under standardized management, providing reliable support for product quality.

Metallographic Testing: Strict control over the internal quality of products is our core advantage. We have built our own metallographic laboratory, and metallographic structure inspection after annealing is included in routine mandatory inspection items. Strict judgment is carried out on key indicators such as spheroidized structure, carbide morphology, decarburization and network carbide. Supported by the lATF16949 quality management system, we realize full-chain control and full-process traceability from raw materialstofinished products. We guarantee product stability from the perspective of internal structure and supply customers with bearing rings of reliable quality.
