[Asia Economy Reporter Oh Hyung-gil] Hyundai Steel announced on the 9th that it has developed alloy steel for reduction gear and its manufacturing technology to target the high-performance material market for electric vehicles, and has obtained the New Excellent Technology (NET) certification from the Ministry of Trade, Industry and Energy.

This technology, jointly developed with Hyundai Motor Company and Kia, involves Hyundai Steel optimizing alloy component design and manufacturing processes, while Hyundai Motor Company and Kia handled material development planning and prototype production.

This alloy steel improves thermal deformation by 48% compared to the steel types used in existing reduction gear parts, reducing noise generated during gear operation, which in turn enhances driving quietness.

Additionally, by securing high-temperature stability, the durability of the reduction gear has increased by more than twice compared to before. Kia plans to apply this alloy steel to the high-performance electric vehicle EV6 GT launching this year and will continue to expand its application to other models.

A Hyundai Steel official stated, "The high-performance alloy steel for reduction gears has superior thermal deformation and durability compared to existing steel types," adding, "By obtaining the NET certification for our independently developed material, we have proven our excellent technological capabilities and expect it to greatly contribute to securing competitiveness in the electric vehicle parts market."
