On August 11, the first batch of 750MPa hot-rolled transmission shaft steel of HBIS Group Tangshan Iron and Steel Co., Ltd. rolled off the production line smoothly. After inspection, the dimensional accuracy, plate shape, and other indicators all met customer requirements. This product has the highest strength level in the domestic hot rolling field. After processing, it will be used in the manufacturing of key transmission parts of heavy-duty vehicles. This marks a new breakthrough in Tangshan Iron and Steel in the field of high-end transmission shaft steel, laying a solid foundation for improving market competitiveness and expanding market share.
