benefits of using hastelloy c22 plate
- Comprehensive Corrosion Resistance: Alloy n06022 sheet has high corrosion resistance in both oxidizing and reducing media, which includes resistance to wet chlorine, nitric acid, and mixed oxidizing acids containing chloride ions.
- Localized Corrosion Resistance: The high resistance to pitting, crevice corrosion, and stress corrosion cracking are the prominent features that Hastelloy c22 plate has. Its Pitting Resistance Equivalent Number (PREN) exceeds 65, significantly exceeding that of 316 stainless steel (approximately 25).
- Weldability: C22 alloy resists grain boundary precipitation in the heat-affected zone (HAZ). This special features is suitable for a variety of chemical process applications in the welded state. This characteristic greatly simplifies the manufacturing process of chemical equipment.

alloy sheet c22 Hot Working and Cold Working
For hot working, the optimum temperature range for alloy C22 sheet is 1150-950°C. After processing, rapid cooling is required to avoid prolonged exposure to the sensitization zone of 540-760°C to prevent the precipitation of harmful phases.
Due to the moderate work hardening rate of Hastelloy C22 n06022 alloy during cold forming, intermediate annealing may be required to relieve stress. Annealing temperatures are typically between 1065-1120°C, followed by rapid water cooling.
Frequently Asked Questions (FAQ)
What makes Hastelloy C22 better at resisting weld corrosion?
During welding, many standard stainless materials experience carbide precipitation in the heat-affected zone (HAZ), leading to intergranular corrosion. Alloy C22 is engineered with low carbon and controlled tungsten levels to resist precipitate formation, allowing it to be used in the as-welded state for most chemical processing applications.
Can Hastelloy C22 be used in high-temperature environments?
Yes. Thanks to its robust nickel base, Alloy C22 maintains strong mechanical integrity and oxidation resistance at temperatures reaching up to 1250°F (677°C), making it ideal for hot chemical process piping.
What is the typical PREN value of Hastelloy C22?
Hastelloy C22 typically possesses a Pitting Resistance Equivalent Number (PREN) greater than 45. This high value confirms its exceptional resistance to localized chloride pitting compared to standard duplex and austenitic stainless steel grades.
