Hastelloy is a nickel-molybdenum-chromium alloy designed for extreme corrosion resistance, excellent mechanical performance, and long-term reliability. It is widely used in chemical processing, marine, aerospace, pollution control, and industrial applications, where conventional stainless steels fail to perform.

What is Hastelloy?

Hastelloy is a family of nickel-based superalloys, engineered for maximum resistance to corrosion, oxidizing and reducing agents, and high temperatures. The most popular grades include Hastelloy C276 and Hastelloy C22, both offering:

  • Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking
  • Superior performance in oxidizing and reducing chemical environments
  • High mechanical strength and durability at elevated temperatures
  • Exceptional weldability and fabrication properties

Hastelloy pipes and tubes are widely used in chemical plants, marine structures, heat exchangers, and pollution control equipment, where reliability and longevity are critical.


Grades of Hastelloy Pipes & Tubes

1. Hastelloy C276

  • Nickel-based alloy with molybdenum, chromium, and iron
  • Outstanding resistance to oxidizing and reducing environments
  • Excellent resistance to strong oxidizers like ferric chloride and nitric acid
  • Ideal for chemical processing, marine, and industrial applications

2. Hastelloy C22

  • Nickel-chromium-molybdenum-tungsten alloy
  • Superior oxidation and reduction resistance, especially in chlorinated acids and saltwater
  • Commonly used in chemical reactors, pollution control systems, and heat exchangers
  • Provides enhanced resistance to pitting and crevice corrosion

Both C276 and C22 maintain high strength, ductility, and corrosion resistance across a broad range of temperatures, making them highly suitable for critical industrial piping systems.
