The fluids used in the manufacture of chemicals are extremely corrosive to the equipment coming into contact with them. This can rapidly lead to expensive repair and/or replacement of equipment and highly disruptive downtime.
A Hastelloy Reactor from TITAN Metal Fabricators offers strong resistance to localized corrosion, stress corrosion and cracking. Specification of Hastelloy as the material of construction for Reactors offers a long-term and highly cost-effective method of corrosion damage avoidance.
Careful analysis of the fluids and processes have led to Hastelloy Reactors being widely used in the process industries, and have proven to be corrosion-resistant in these extremely harsh environments.
Life Cycle of Benefits of Hastelloy Reactors
Hastelloy Reactors are highly cost-effective over the entire life cycle of the equipment. Properly maintained, they can operate for decades, making them a very economical choice material selection over other available reactive metals.
Hastelloy Reactors can:
- Deliver many years of economical service life
- Eliminate expensive downtime due to equipment failure
- Provide outstanding Corrosion Resistance
- Produce high heat transfer efficiency
- Accommodate high steam pressure
- Fully welded metal construction
- Removes possibilities of process fluid leaks
Hastelloy the Metal
For its myriad applications, the processing industries are constantly in pursuit of highly reliable materials. Hastelloy’s beneficial performance has led to wide acceptance and growth of its use in the areas of energy, health and environmental, oil and gas, and pharmaceutical.
Hastelloy Reactors are widely accepted by plant operations management and maintenance specialists who appreciate their toughness and ability to withstand very aggressive fluids.
The attributes 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 Corrosion Resistance
Hastelloy Reactors are suitable for applications in the chemical processing, pharmaceutical, agricultural, food, petrochemical, and power industries. They are frequently found in chemical, petrochemical, oil & gas and other severe industrial manufacturing environments.
A Hastelloy Reactor performs robustly in the harsh fluids inherent these processes. These chemicals are frequently at very high temperature, testing the material’s strength and corrosion resistance, yet a HASTELLOY Reactor is resilient.
TITAN Hastelloy Reactors are used in a wide variety of oxidizing and reducing environments. 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.
