Hastelloy C22 flanges are particularly effective in environments containing strong oxidizers such as ferric and cupric chlorides, chlorine, and nitric acid mixtures. They provide exceptional resistance to localized corrosion such as pitting and crevice corrosion, making them suitable for use in scrubbers, reactors, and pressure vessels.
Hastelloy C2000 flanges are an advanced nickel-chromium-molybdenum-copper alloy designed for extreme chemical environments. Their unique composition makes them resistant to both oxidizing and non-oxidizing chemicals. These flanges are ideal for modern chemical plants where multiple aggressive media are present in one process.
Hastelloy B2 flanges are formulated for excellent resistance to pure hydrochloric acid and other strongly reducing media. They are highly resistant to stress corrosion cracking and show excellent performance in a wide range of non-oxidizing acid environments, making them a top choice in chemical transfer and acid regeneration systems.
Hastelloy B3 flanges are the next generation of B-series alloys, offering improved thermal stability and resistance to spontaneous aging. This makes them suitable for more demanding applications where temperature fluctuation and aggressive chemical exposure are constant. B3 flanges also resist pitting and hydrogen embrittlement better than earlier versions.
