Hastelloy C22 Plates are used across multiple demanding industries:

• Chemical Processing: Reactors, scrubbers, piping systems, and heat exchangers handling mixed acid solutions.

• Petrochemical Industry: Process vessels and components exposed to hydrocarbons, chlorides, and aggressive catalysts.

• Marine Engineering: Ideal for desalination plants, offshore structures, and seawater processing due to excellent chloride resistance.

• Aerospace: High-temperature parts exposed to corrosive atmospheres in aircraft and spacecraft applications.

• Pollution Control: Equipment for flue gas scrubbers, stack liners, and chemical neutralization systems.

• Pharmaceutical Manufacturing: Sterile environments requiring resistance to aggressive cleaning agents and chemicals.

By offering customizable sizes and finishes, DLX ensures that customers can integrate C22 Plates seamlessly into their systems.

Global industries are increasingly exposed to harsh operating environments. The demand for alloys like Hastelloy C22 is rising due to:

1. Stricter Environmental Regulations: Pollution control systems require materials with high chemical resistance.

2. Expanding Chemical Processing Capacity: Plants are handling more aggressive reactions, requiring better material reliability.

3. Marine and Offshore Development: Desalination projects and offshore drilling demand robust alloys resistant to seawater and chlorides.

4. Aerospace Expansion: Advanced aircraft and space missions need lightweight but corrosion-resistant alloys.

5. Pharmaceutical Growth: Manufacturers require sterile, high-purity equipment made from non-contaminating alloys.

DLX recognizes these industry dynamics and provides high-quality solutions to meet growing global demands.
