Our Inconel 625, 617, and 690 plates are engineered to power through the toughest conditions in power plant components. These nickel-based alloys are built for strength, corrosion resistance, and performance in high-heat, high-stress environments. Inconel 625 thrives in acidic and chloride-heavy settings, perfect for boiler tubes and chemical-exposed parts up to 1800°F (982°C). Inconel 617 takes on extreme heat up to 2000°F (1093°C), making it ideal for superheaters and turbine components. Inconel 690 is a champ at resisting stress corrosion cracking, especially in nuclear reactors and flue gas systems. Available in thicknesses from 1/8″ to 2″, we customize these plates to fit your exact component designs.
Industry Analysis
