Baosteel successfully developed ultra-high strength hot rolling engineering machinery steel
In the future, large-tonnage cranes and pump trucks will become even heavier, but there's no need to worry about arm strength anymore. Currently, only a handful of top international steel manufacturers are capable of producing 960 MPa high-strength hot-rolled steel used in construction machinery. Recently, Baosteel successfully developed this advanced material, filling a critical gap in the domestic market.
Today, both domestic and global construction machinery industries rely on 960 MPa high-strength engineering steel to manufacture booms for large equipment, significantly enhancing the stability and lifting performance of these components. Over recent years, demand for this type of high-strength steel has been steadily rising. It is projected that consumption will reach between 800,000 and 1,000,000 tons this year. Due to its high strength, this material was previously entirely imported, limiting supply and increasing costs.
For many years, Baosteel has been at the forefront of developing high-strength engineering steel, with a yield strength of up to 700 MPa. Leveraging its production, sales, and R&D advantages, the company has consistently provided stable supplies to downstream industries. Building on this foundation, Baosteel’s hot rolling production and sales research team closely followed industry trends and analyzed the growing demand for 960 MPa materials. Last year, they initiated product development based on the principles of enhancing competitiveness and maximizing value.
Through independent innovation, the team conducted extensive research on material composition and process optimization, overcoming equipment limitations within just six months. The trial production of the new product was a complete success.
Currently, Xugong Group, one of the leading players in China’s construction machinery sector, has confirmed that the performance and quality of this steel are stable and suitable as a viable alternative to imported products. This marks a significant step forward in China’s ability to produce high-quality, high-strength steel domestically, reducing reliance on foreign suppliers and boosting the competitiveness of the entire industry.
The steel crankshaft is a critical component in internal combustion engines, such as those found in automobiles, marine vessels, and industrial machinery. It is responsible for coverting the reciprocating motion of the pistons into rotational motion, which ultimately drives the wheels or other machinery.
