JAKARTA The global automotive industry has just witnessed a significant leap in safety material technology thanks to the collaboration between the well-known car manufacturer, Chery, and the giant steel company, HBIS Group.

The two companies officially announced the successful development and testing of hot-plated steel (hot-formed steel) with ultra-high strength and toughness to reach 2400 Mega Pascal (MPA). This achievement not only marks a major increase in Chinese material science, but also sets new standards for vehicle security globally.

In comparison, the world record so far for ultra-high-power steel in a mass production car held by Xiaomi SU7 at 2200 MPa, made Chery and HBIS' 2400 MPa breakthrough a new milestone in automotive material engineering.

Reporting from CarNewsChina, Tuesday, December 9, hot printed steel plates are an inseparable component of modern safety structures, forming vital backbones in critical parts such as A/B pillars, door-to-door beams, door rings, and floor-crossing beams (floor crossbeams). These components are very important in protecting passengers and maintaining car structural integrity during hard collisions.

Traditionally, the industry relies on heat-printing steel with a power range of 1300 to 1800 MPa. The challenge engineers have faced so far is how to increase higher power without compromising other essential properties, such as toughness, stability, and formability (formability). A complex engineering dilemma. Through this collaboration, Chery and HBIS managed to overcome these barriers, producing materials that not only increased strength but also maintained excellent processing performance and stability.

This newly developed 2400 MPa heat-printing steel offers three main advantages: Increased Safety through a significant increase in the impact-resistant power of the safety component; Potential Heavy Crossing (Lightweighting) that allows for the use of thinner specifications, opens up great opportunities to reduce overall vehicle weight in order to increase fuel efficiency, reduce emissions, and improve driving performance; as well as Property Balance that combines high power with extraordinary shape resilience and capability. This combination is effective in addressing industrial general problems where high-power materials tend to be fragile and difficult to process, ensuring this material is feasible for bulk manufacturing.

According to Chery, the new material has gone through a stringent set of tests, including real parts of print trials, installations on vehicles, and repeated validation, particularly for applications on the door-to-door anti-collision beams. The test results have confirmed stable mechanical properties, controlled formation process windows, and precision dimensional accuracy, signaling its readiness for mass production in high-power safety applications.

Going forward, Chery and HBIS plan to expand the use of this revolutionary material to other vital structural components, such as door rings, elongated beams, and cross beams.
