· ArcelorMittal and Honda will cooperate with internal and external door knocker systems

According to foreign media reports, ArcelorMittal and Honda demonstrated the world's first outer and inner door ring system at the WCX18 event earlier this month to improve the balance between vehicle strength and performance. Sex, while reducing weight for the vehicle. The two companies jointly designed the system for the 2019 Honda Acura RDX.

The inner door ring includes five different measuring instruments from ArcelorMittal, which uses the patented press hardenable steel (PHS), the Usibor 1500, while the outer door ring contains four Usibor 1500 measuring instruments. All types of Usibor steel sheets are finished in the blanking company and then sent to the ArcelorMittal billet custom factory in Detroit for processing and laser ablation technology.

Usibor is a coated steel that removes coatings and prepares welding edges to complete a safe soldering operation while preserving the corrosion resistance around the weld area.

After the laser ablation is completed, the steel is welded together, and its multi-stage quality control ensures its accuracy. The rough is sent to the hot-stamper and processed into finished parts for the car.

In addition to improving the performance and safety of the vehicle, it also provides a five-star rating for the narrow narrow offset crash test, and its door knocker scheme also supports the vehicle's lightweight targets. Honda has increased the application of super-strength steel on RDX models by more than 50%, which is 19 kg/42 lbs less than the previous models.

This exterior door ring design replaces the traditional multi-part spot welding design, which can also be used in both the Pilot and Odyssey models.
