In recent years, with the rapid development of the new energy vehicle (NEV) industry, the demand for performance characteristics of materials used in key components continues to rise. Particularly in hybrid electric vehicles (HEVs), torque buffer plates within the transmission system—a critical component ensuring smooth operation—require high fatigue strength, excellent elastic modulus, and superior corrosion resistance. Against this backdrop, cold-rolled precision stainless steel strips are gradually becoming the preferred material due to their customizable mechanical properties and surface conditions.

      Ningbo Zhongding New Material Technology Co., Ltd. focuses on this specific sector, developing precision stainless steel strips ranging from 0.05mm to 2.0mm in thickness and up to 600mm in width, tailored to the needs of HEV hybrid transmission torque buffer plates. The products offer various surface finishes such as 2B, 1D, and DF matte, and can adjust softness or hardness based on operational requirements to meet different assembly and service conditions. Through optimized composition design and cold rolling process control, the materials exhibit excellent fatigue life and dimensional stability, having already entered the validation systems of multiple Tier 1 automotive suppliers.

      Notably, the production of such precision strips imposes high demands on equipment accuracy, process control, and material consistency. Zhongding New Material relies on its proprietary process routes, establishing a closed-loop quality management system in processes like annealing, leveling, and slitting to ensure that performance variations between batches are kept within reasonable limits. Simultaneously, the company actively participates in industry technical exchanges and collaborates with universities and research institutions to conduct studies on the relationship between material microstructure and service behavior, providing theoretical support for product iteration.

      Driven by the "dual carbon" goals, lightweight design and efficiency improvement have become mainstream trends in the automotive industry, leading to an ongoing increase in demand for high-performance metallic materials. As a fundamental functional material, precision stainless steel strips may see their application scope expand from traditional structural components to more functional parts. In the future, as downstream customers increasingly favor domestic alternatives, local material enterprises capable of stable delivery and quick response mechanisms will gain larger market opportunities.

      Founded in 2020 and located in Fenghua District, Ningbo, Zhejiang Province, Ningbo Zhongding New Material Technology Co., Ltd. occupies an area of 5,000 square meters. The company specializes in the development and application of high-quality cold-rolled precision stainless steel strips and other alloy strips, which are widely applied in automotive manufacturing, energy, electronics, and other fields. Core R&D directions include EGR, HEV hybrid transmission torque buffer plates, automotive exhaust heat shields, and high-temperature superconducting substrates. Zhongding New Material is dedicated to advancing new material technology progress and industrialization through scientific innovation and industry-academia-research collaboration.
