The fluids used in the processing of chemicals, petrochemicals, and in oil & gas are extremely corrosive, which can rapidly lead to repair and/or replacement of process equipment causing expensive and disruptive downtime.

Research and testing have been shown Hastelloy Pressure Vessels to be highly corrosion-resistant in these extreme environments, and have led to Hastelloy being widely specified as the material of construction in these industries. A Hastelloy Pressure Vessel from TITAN Metal Fabricators offers strong corrosive resistance to localized corrosion, stress corrosion and cracking.

Life Cycle Benefits of a Hastelloy Pressure Vessel

Hastelloy Pressure Vessels are highly cost-effective over the entire life cycle of the equipment.  Properly maintained, they can operate for decades, making Hastelloy a very economical choice over other available metals.

Hastelloy Pressure Vessels can:

  • Deliver many years of economical service life
  • Eliminate expensive downtime due to equipment failure
  • Provide outstanding corrosion resistance
  • Provide excellent stress cracking resistance

Hastelloy the Metal

The processing industries are always on the hunt for resilient and cost-effective materials.  Because of its highly corrosion-resistant material structure, Hastelloy is widely specified for fabrication in the areas of energy, health and environmental, oil and gas, and pharmaceutical.

Hastelloy Pressure Vessels are hugely recognized by plant operations management and maintenance specialists for their extreme durability and capacity to fight against very destructive fluids.

The positive characteristics of the Hastelloy family of alloys include high resistance to uniform attack, outstanding localized corrosion resistance, excellent stress cracking resistance, and ease of welding and fabrication. There are ten different alloys in the Hastelloy family, each with its own unique characteristics that make them desirable as materials of construction for many different manufacturing processes.

  • Hastelloy B-3
  • Hastelloy C-22
  • Hastelloy C-22HS
  • Hastelloy C-276
  • Hastelloy Hybrid-BC1
  • Hastelloy C-2000
  • Hastelloy C-4
  • Hastelloy G-30
  • Hastelloy G-35
  • Hastelloy N

Please see Applications of Hastelloy for a more in-depth look at additional uses for Hastelloy that includes some comparative corrosion resistance data, media, concentrations and temperatures.

Hastelloy Corrosion Resistance

A Hastelloy Pressure Vessel will often be specified for chemical, petrochemical, oil & gas and other severe industrial manufacturing environments. These chemicals are frequently heated to very high temperature, testing the material’s strength and corrosion resistance, yet a Hastelloy Pressure Vessel is resilient when its surfaces come into contact with these hostile fluids.

To view a list of process materials where Hastelloy is commonly used, please visit Applications of Hastelloy.

For a general guide on corrosion resistance, temperatures and concentrations please see TITAN’s publication, “Corrosion Resistance of Metals in Various Chemical Media” for additional information. *

*Note: Final selection of material must be based on actual evaluation of the metal in the corrosive medium.

Haynes International, Inc. is the owner of the Hastelloy® trademark and developer of the Hastelloy family of corrosion-resistant alloys.
