Compatibility
The compatibility information presented below is provided as a guide and is based
on available data generated by Albemarle Corporation, our experience with similar
products, and from literature. It is the user’s responsibility to develop data with the
actual materials of construction and at the intended use conditions.
At ambient temperatures, dry aHBr (dew point of –40 °C) is expected to be
compatible with carbon steels, Types 304/347 and 316L stainless steel, Hastelloy®
B and C, Inconel®, Monel 400, Nickel 200, platinum, fluoropolymers,
fluoroelastomers, halogenated polyesters, polyethylene and polypropylene.
Wet HBr (with water content above the dew point) is very corrosive to metals.
Tantalum and niobium are suitable for use in wet HBr service at ambient
conditions.
For additional information, please contact us.
Safety and Handling Information For specific safety, handling and toxicity information, please refer to the current
Material Safety Data Sheet (MSDS).
