What is C22 used for?
Why choose the C-22?
C-22 is used in severely corrosive media with high chloride and high temperature applications such as buffer solutions, active pharmaceutical ingredients (APIs), fabric softeners, cleaning supplies, and fish, soy and chili sauces.
C-22 is a good alternative when super-austenitic stainless steels (AL-6XN, 904L and 254 SMO) and duplex stainless steels (2205 and 2507) cannot withstand extremely corrosive media. This is because it is a nickel-chromium-molybdenum-tungsten alloy that has better overall resistance to uniform and localized corrosion than any other Ni-Cr-Mo alloy such as Hastelloy C-276, C-4 and Alloy 625 .
The alloy is approved by the ASME BPE standard, which establishes several specifications in Section MM (Metallic Materials), and is approved by the U.S. Food and Drug Administration (FDA).
1. Good Manufacturing Practices
Selecting the correct sanitation equipment and materials to avoid corrosion is a best practice in most processing environments.
2. No microbial contamination
No crevices, pitting, or product buildup.
3. Product availability
CSI stocks over 65,000 feet of pipe and thousands of fittings.
4. Avoid changing equipment
Superalloys provide a good return on investment by reducing product loss and maintenance time repairing and replacing corroded parts.
