Hastelloy Alloys Products
Product Overview
Hastelloy alloys are nickel-based corrosion-resistant materials designed for extreme environments involving strong acids, oxidizing media, and high temperatures. These alloys offer excellent resistance to pitting, crevice corrosion, and stress corrosion cracking.
Common grades include Hastelloy C276, C22, B2, and X, which are widely used in chemical processing, marine engineering, flue gas desulfurization (FGD), and high-temperature applications.
Available product forms include pipes, tubes, plates, bars, fittings, and flanges, all manufactured to international standards with full traceability.
