H-Solution Technical Conference(Online)
Amid the COVID-19 pandemic, Hyundai Steel held the 1st H-Solution Technical Conference in an online format.
The conference was held from December 2-10, 2020, in which nine subject areas were covered over four sessions. The conference attracted 881 participants from 130 companies around the world, demonstrating great interest in automotive steel products from Hyundai Steel. Through the conference, Hyundai Steel demonstrated to global customers and academic researchers the company’s differentiated R&D capabilities, with presentations not only on our customer-tailored automotive solutions brand 'H-Solution', but also on 'Future Automotive Materials' and 'Filler Wire Hot Stamping TWB Welding Technology.' Furthermore, the conference served as a valuable venue to promote the high-quality automotive materials unique to Hyundai Steel, and to showcase the eco-friendly technologies and services we provide in response to the changing automotive market.
Going forward, we plan to explore effective ways to create synergies in the development of future Automotive Steel Plates by continuing our engagement with the global customers who participated in the conference.
Ultra High Strength Automotive Steel Brand 'ULTREX'
In September 2020, Hyundai Steel launched ULTREX, an ultra-high-strength steel product with a tensile strength of 60kgf1) or higher, which has excellent strength and formability.
ULTREX(Ultra+sTRength+Excellent) is a core material optimized for use in automotive panels, structural components and chassis parts. Containing alloying elements in optimal ratios, ULTREX is produced using a meticulously controlled cooling process, giving it high strength and outstanding formability.
- 1) A gravitational metric unit of force, also called kilogram-force, which refers to the magnitude of force exerted on an object with a mass of 1kg under the standard gravitational acceleration on Earth.
The main applications of ULTREX include MS(Martensitic) and ACP(Advanced Complex Phase). Of these, MS is the product with the highest strength and is used in parts that absorb shock, such as the front bumper beam. ACP steel has excellent bendability and weldability, and is used for structurally complex parts, such as the front pillar inner lower panel, that need to be welded to other parts.
In addition, Hyundai Steel is developing AMP(Advanced Multi-Phase) and Q&P (Quenching & Partitioning), which are third-generation steels. Third-generation steels, with tensile strengths and elongation rates higher than existing ultra-high strength steels, can be used in parts requiring high strength and formability. With ULTREX, we are promoting the quality and technology of our high strength steel, and we plan to lead the mobility materials industry by taking an active part in the supply and development of materials for the eco-friendly automobiles of the future.
