High-Performance Alloys

Among stainless steels and alloys, these high-performance alloys provide superior functionality. Features include high corrosion resistance, heat resistance, high strength and other special features such as not being magnetizable. These alloys are used in harsh environments under tough conditions in advanced technology fields such as desalination, atomic power, semiconductors, solar cells and fuel cells.

Although standard stainless steels do not readily corrode, under harsh conditions, corrosion may lead to holes in the material. By adding optimal quantities of chromium, molybdenum, nickel and other alloying metals, we improve stainless steel to provide overall corrosion protection as well as improve resistance against grain boundary corrosion, pitting and crevice corrosion, and stress corrosion cracking. Stainless steels and nickel alloys with powerful corrosion resistance are used in harsh, corrosive environments such as found in desalination systems, marine structures, fuel cells and atomic power generation plans.
