As the steel industry accelerates its transformation and upgrades, the entire supply chain is also advancing, driven by the emergence of new sectors like new energy, advanced materials, and high-end equipment. This shift is gradually steering steel development toward higher quality, fostering a continuous upgrade in production automation and intelligence.
In modern production lines, changes are not limited to the “hardware” but also include key trends such as lightweighting in the automotive industry. As the demand for safety increases, the vehicle body—which serves as a primary carrier of passive safety—relies heavily on the quality of materials and manufacturing processes to determine critical performance indicators like safety and rigidity.
Driven by goals to reduce both carbon output and energy usage, the development and application of lightweight materials have been prioritized. Hot-formed steel has become one of the main choices for automotive body materials due to its irreplaceable advantages in addressing the challenges of lightweighting and the forming of high-strength steels.
Aluminum-silicon coatings, known for their high-temperature resistance, low density, wear resistance, high thermal conductivity, and low expansion coefficient, are the most widely used coatings on hot-formed steel. These coatings are extensively utilized in the automotive industry.
Han’s Laser, a pioneer in automotive industry innovation, excels in providing lightweight solutions to global clients. Han’s Laser’s research and development in integrated hot forming door ring laser tailor welding technology stand out, supported by a plethora of successful application cases.
