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.

In a high-temperature environment, materials face issues related to strength, oxidation and corrosion. Nickel is effective at improving high-temperature strength while chromium, silicon and aluminum provide protection against oxidation. Materials made from stainless steel with such elements mixed in are referred to as heat-resistant stainless steels. Other factors taken into account for high-temperature environments include creep strength and heat cycle fatigue. Heat-resistant stainless steels are used in heat exchangers, pressure containers and heat treatment furnace components.
