Ansteel Co., Ltd. has successfully developed 460 MPa grade high-strength and toughness steel for locomotives.

Ansteel Co., Ltd. recently successfully developed a 100mm thick, 460MPa high-strength and toughness steel for locomotives, the first in the world. This product can withstand extreme temperatures of -50°C, fully meeting the stringent requirements of rail transit equipment in cold regions.

Through innovative composition design and optimized preparation processes, this development effectively addressed technical bottlenecks commonly encountered in thick, high-strength steel, such as segregation, inclusion control, and microstructure uniformity, ensuring the stability of material properties. The product's synergistic combination of thickness and strength and toughness reaches industry-leading levels, providing a core material guarantee for the long life and high reliability of rail transit equipment, including Fuxing locomotives, and further enhancing train safety in extreme environments.
