President Tak Jeong, ‘We will provide solutions that customers need’
POSCO won the Gold Award in the technology category at the 26th International Stainless Steel Forum hosted by World Stainless Association.
The technology that won the Gold Award this time was the high-performance ferrite stainless steel ‘430RE (Ridging Endurance)’ manufacturing technology. As the technology was selected as the best case of stainless-related technology development this year, POSCO’s technological skill was recognized worldwide.
Recently, as home appliance makers make large-scale washing machines and drying machines, it has become important to improve the formability of the drum bottom and to reduce the defect of stripe pattern on the surface.
In addition, as the high-speed rotation performance of the drum is required to save water and power during spin-drying, the welding method with excellent bonding strength is preferred over the method (Lock Seaming) of connecting by folding and compressing the plate material when connecting the center of the drum.
Accordingly, POSCO developed 430RE, a specialized steel grade that has features such as enhanced formability, anti-ridging, and corrosion resistance at welds compared to existing steel types, and plans to expand its supply to overseas as well as domestic home appliance companies.
POSCO President Tak Jeong said, “The development of steel grade through long-term collaboration in active response to customer needs was highly evaluated. We will continue to provide solutions to develop products that customers need.”
