[Alpha Biz= Kim Jisun] SeAH Group has become the first company in South Korea to develop and commercialize superalloy technology, previously held only by a few advanced countries such as the United States and Japan. Superalloys are critical next-generation materials used in aircraft and rocket engines, as well as nuclear reactor gas turbines.
According to the steel industry on August 17, SeAH Changwon Integrated Special Steel, an affiliate of SeAH Group, will deliver prototype superalloy materials at the end of this month to Hanwha Aerospace for use in turbine engine retainers—components that secure blades inside aircraft engines. “Prototype production has already been completed, and we are currently discussing details with Hanwha Aerospace for full-scale supply,” a SeAH official said.
Superalloys are advanced materials made primarily from nickel and cobalt, designed to withstand extreme environments exceeding 700°C. The material SeAH has developed can endure ultra-high temperatures above 900°C, placing it among the highest-grade alloys. This marks the first successful commercialization of such a superalloy in Korea, opening the door for broader applications in aerospace and energy industries.
