Recently, Wusteel Company of Hebei Iron & Steel Group successfully delivered a batch of newly developed high-end low-temperature pressure vessel steel products, specifically engineered for a premium client. This marks the first domestic production of such steel, breaking foreign technological monopolies. The product will be used in manufacturing critical components of a 1,500-cubic-meter large-scale high-pressure buffer tank, signifying another significant breakthrough in China's high-end steel materials sector.

Wusteel Company remains steadfast in its special steel development strategy. Centering on the objectives of “ultimate cost efficiency, ultimate operational efficiency, ultimate energy efficiency, and ultimate brand excellence,” it is vigorously advancing key projects and critical tasks to sprint toward the fourth quarter, ensuring the successful completion of its annual objectives. To continuously enhance the brand influence of Wusteel's wide plate products, the company leverages its technological R&D strengths. Building upon the approval of its high-end pressure vessel steel by the China Special Equipment Inspection and Research Institute, it continues to deepen its expertise in low-temperature pressure vessel steel. Successively launching multiple domestically first-to-market products, the company effectively leads market trends and meets the demands of high-end clients.

In this collaboration, Wusteel actively responded to customer requirements by developing a new type of low-temperature pressure vessel steel with outstanding comprehensive properties, meeting the client's stringent demands for safety, efficiency, and environmental performance. Through unique composition design and heat treatment processes, this steel maintains exceptional low-temperature toughness while ensuring ultra-high strength. It retains core impact absorption energy of 100 joules in extreme environments as low as -70°C, delivering outstanding mechanical performance that has earned high recognition from the customer.

The successful development and application of this product not only enhances China's self-reliance in the specialty steel sector but also provides crucial material support for the localization of key equipment in industries such as energy, chemical processing, and gas storage and transportation.
