We supply perfect products that have passed UT inspection not only in stainless steel grades but also in Ni steel grades such as Incoloy 800, Inconel 625, 690, and 718 .

The durability and corrosion resistance of tubes used in reactor steam generators, nozzles, and high-temperature components are essential for the long-term, stable operation of nuclear reactors.

TRIS is developing a new steel grade aimed at extending material lifespan and preventing corrosion cracking — an area in which TRIS also has proven experience.
