BaoSteel has recently delivered 60 tonnes of ultra high strength steel for manufacturing of truck mounted crane booms to substitute imported steel. As the first steel mill in China to achieve import substitution of BS800E and BS960E hot-rolled ultra-high strength steel, Baosteel has been at the forefront of independent R&D and production of ultra-high strength steel.

Three years ago, major domestic construction machinery users have repeatedly put forward that they hope that BaoSteel will play the leading role of domestic steel mills, achieve product breakthroughs, help users no longer be subject to foreign steel mills in such products, and promote the update and iteration of heavy equipment in major countries.

Construction machinery as a heavy weapon of a large country is a symbol that reflects the national manufacturing level, and ultra-high strength advanced materials are the cornerstone of the manufacturing of heavy equipment in a large country. BaoSteel joins hands with leading users in the construction machinery industry to continuously innovate around the application and upgrading of new products, new processes and new technologies.

BaoSteel’s recently commissioned thin-gauge ultra-high-strength steel production line, which has improved processing and molding accuracy. With latest cooling process, the internal stress of the steel plate is effectively improved, and the phenomenon of slitting side bending is effectively improved. The surface oxide layer is more uniform, which effectively solves the problem of black ash. The result is ultra-high strength, high plate shape quality, high-quality surface, good low-temperature toughness, weldability, and cold formability.

With this, BaoSteel’s heat treatment products will continue to improve product quality, supply capacity and resource assurance, and further improve the overall competitiveness.
