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.
