Chemical Properties
The Hastelloy C22 Sheet excels in resisting aggressive chemicals:
- Acids: Outstanding against nitric, hydrochloric, sulfuric, and acetic acids.
- Oxidizing Media: Handles wet chlorine and ferric/cupric chlorides effortlessly.
- Reducing Environments: Robust in formic acid and brine solutions.
However, prolonged exposure above 1250°F (677°C) may compromise its properties due to detrimental phase formation.
Things to Note (Limitations)
While the Hastelloy C22 Sheet is exceptional, consider these restrictions:
- Temperature Limits: Avoid service above 1250°F to prevent phase degradation.
- Cold Work Sensitivity: Excessive cold forming (>7% elongation) requires re-annealing for optimal corrosion resistance.
- Specialized Fabrication: Requires skilled handling for complex shapes.
Corrosion Data for Hastelloy C22 Material
The C-22 alloy offers remarkable corrosion resistance:
- Atmospheric Exposure: Minimal degradation in humid or salty conditions.
- Mild Chemical Corrosion: Rates as low as 0.1-0.5 mpy (mils per year) in acetic acid.
- Severe Environments: Outlasts Hastelloy C276 sheet in chloride-rich settings.
Data from lab tests confirms its edge over competing alloys.
Welding and Manufacturing Tips
Maximize the potential of your Hastelloy C22 Sheet with these insights:
- Welding Methods: Use GTAW (TIG), GMAW (MIG), or SMAW (Stick) with matching filler (ERNiCrMo-10).
- Annealing: Post-weld annealing at 2050°F (1121°C) followed by water quenching enhances performance.
- Forming: Cold work is preferred; intermediate annealing may be needed for extensive shaping.
- Machining: Use rigid, sharp tools to manage work hardening.
Our customized size options ensure seamless integration into your manufacturing process.
What Customers Say About Our Hastelloy Material
Frequently Asked Questions
What is the difference between Hastelloy C22 and C276?
