Hastelloy
What is a Hastelloy?
Hastelloy is a high-performance corrosion-resistant metal alloy made primarily of nickel with varying amounts of molybdenum, chromium, cobalt, and iron. It is designed for extreme chemical resistance, especially against strong oxidizers, acids, and high-temperature environments. It is widely used in harsh processing industries such as chemical plants, marine systems, and nuclear reactors.
Asiad Steel Industries supplies premium Hastelloy alloys including C22, C276, and X grades in various forms like pipes, sheets, tubes, and components.
