POSCO has achieved a significant milestone by developing high ductility steel and armor steel specifically for naval vessels, thereby becoming the first company in South Korea to secure this technology and gain certification from Korea Register (KR) on January 12. The high ductility steel is designed to absorb external shocks, considerably improving its resistance to destruction and deformation during impacts. Compared to traditional shipbuilding steel plates, this new material enhances ductility by over 35%, and simulation tests indicate an approximately 58% increase in shock absorption during collisions with vessels or floating objects, which is crucial for minimizing structural damage.

Moreover, POSCO has also developed armor steel to improve the safety, maneuverability, and operational efficiency of naval vessels. This new armor steel is about 30% thinner than conventional materials used in shipbuilding, allowing for its application in critical areas such as the command bridge, radar systems, and advanced weaponry zones. This weight reduction contributes to enhanced resistance to rolling effects, improving the vessel's stability and resilience. The company anticipates that these advancements will play a pivotal role in boosting the capabilities of the South Korean Navy's next-generation vessels and increase the competitiveness of local shipyards.

Looking ahead, POSCO's innovations are expected to have broader implications beyond domestic shores. The company envisions applying its new materials in various international projects, including those involving naval vessels in South America and Southeast Asia, as well as maintenance, repair, and overhaul (MRO) services for the U.S. Navy. This is expected to contribute to the expansion of South Korea's defense exports and establish a stronger foothold in the global naval vessel market, reinforcing the nation's position in the K-defense sector.
