Hastelloy Alloys
Hastelloy Alloys
Hastelloy Alloys are a group of high-performance metal alloys primarily composed of nickel, with varying amounts of molybdenum, chromium, and iron. Known for their excellent resistance to corrosion, particularly in harsh environments, Hastelloy alloys are widely used in industries such as chemical processing, aerospace, and power generation.
Key Features of Hastelloy Alloy
Corrosion Resistance
Exceptional resistance to a wide range of acids, including sulfuric, hydrochloric, and phosphoric acids.
High-Temperature Resistance
They perform well in high-temperature environments, maintaining strength and resisting oxidation.
Mechanical Strength
Hastelloy alloys exhibit high tensile strength and durability under both high temperature and pressure.
Common Applications
Chemical Processing
Used in reactors, heat exchangers, and pipes due to their resistance to aggressive chemicals.
Aerospace
Components like turbine blades and exhaust systems where high strength and heat resistance are required.
Power Generation
For parts exposed to high temperatures and corrosive environments, such as in nuclear and fossil fuel plants.
Popular grades of Hastelloy include Hastelloy C-276, Hastelloy C-22, and Hastelloy B-2, each suited for specific applications based on their chemical composition and resistance properties.
