What are the primary elemental components of Hastelloy alloys_________________?
Show answer Hide answer
Answer: B. nickel, molybdenum etc
Explanation
Hastelloy alloys are classified as nickel-base superalloys containing significant amounts of molybdenum. The combination of nickel and molybdenum provides exceptional resistance to severe chemical attack. Other alloying elements like chromium and tungsten are also added to enhance specific properties. Superalloys are high-performance materials capable of functioning at extreme temperatures and pressures. Molybdenum helps protect the alloy matrix against pitting and crevice corrosion mechanisms. These advanced metallic formulations are specifically developed for aggressive industrial environments.
Chemical processing plants use Hastelloy piping and reactors to handle highly corrosive acids. Air pollution control scrubbers utilize these superalloys to withstand harsh chemical solutions. Aerospace and marine engineering applications benefit from their resistance to aggressive media. Aluminium and copper alloys form brasses and bronzes with different mechanical characteristics. Nickel and copper alloys like Monel offer good marine corrosion resistance but differ in composition. Standard carbon steels lack the specialized alloying elements required for extreme chemical resistance.
