HISTORICAL DOCUMENT. Aqueous hydrofluoric acid (HF) is commercially available in 48% and 70% solutions. Commercial anhydrous hydrogen fluoride (AHF) contains less than 400 parts per million by weight (<400 wt ppm) water. Although this report is intended as a guide for handling commercial HF and AHF, additional information is given to aid users of HF who encounter other concentrations.

This technical report presents general information on materials commonly used for storing and handling commercial grades of aqueous hydrofluoric acid (AqHF) and anhydrous hydrogen fluoride (AHF). Some materials generally avoided are also discussed. This report is intended for end users, designers, and suppliers of equipment for use with AqHF and AHF. These include, among others, workers in process industry plants, engineering and construction designers, and suppliers of equipment such as pumps, valves, and hoses. This information is useful for initial design and for cost estimates of equipment to handle most commercial AqHF and AHF. The report addresses AqHF and AHF purchased to normal commercial quality that do not contain impurities liable to affect their inherent corrosion characteristics. Testing in the service environment typically indicates a material’s suitability for use with AqHF and AHF. This report does not include all materials that might be resistant and is not intended to limit the consideration and testing of other materials.
