Recently, Hebei Iron and Steel Group's TANGSHAN IRON AND STEEL CO., LTD successfully rolled out China's first 2GPa super anti-hydrogen embrittlement hot-forming steel. This breakthrough material boasts significantly enhanced resistance to hydrogen embrittlement and is slated for use in manufacturing single and composite structural components for passenger vehicle bodies. It not only supports the industry's lightweighting goals but also greatly enhances vehicle safety performance.

Hydrogen embrittlement occurs when hydrogen atoms mix into a metal during solidification and subsequently aggregate at metal defects to form hydrogen molecules. The immense internal pressure created can lead to cracking in the material. If such materials are used in critical automotive components like crash beams, it could jeopardize vehicle safety.

To address this issue, Tangsteel has employed groundbreaking niobium microalloying technology, optimizing the steel's microstructure to significantly improve its resistance to hydrogen embrittlement.

Tangsteel's development of this high-performance steel reflects its commitment to leading-edge innovation in materials science. Highlights of the production process include:

Advanced Process Innovation: The production team overcame challenges across the entire process chain, from composition design and hot rolling to coiling and continuous annealing.

Stringent Control: Strict regulation of process parameters ensured stable and reliable performance across all key metrics.

Market Orientation: Focused on cutting-edge automotive needs, this material aligns with trends in lightweighting while offering unparalleled safety enhancements.

This development represents a milestone in China's steel industry, marking a transformation from traditional steel production to high-performance material manufacturing. Tangsteel's achievement in creating 2GPa super anti-hydrogen embrittlement hot-forming steel underscores its leadership in high-end specialty steel and materials innovation.
