Hydrofluoric acid is used, along with nitric acid, in stainless steel pickling solution and paste preparations. Its main function is to loosen and help remove scale deposits.

Corrosion Resistant Metals Materials Selection Guide selection of stainless steel for handling nitric acid

Stainless Steel. Duplex stainless steels have a two-phase microstructure of austenite and ferrite grains. This structure gives these materials a combination of attractive properties, including strength, ductility, and corrosion resistance. Alloy 2507 super duplex, ferritic-austenitic stainless steel is well-suited for service in highly selection of stainless steel for handling nitric acidCorrosion tables Sandvik Materials TechnologyThe corrosion data in this section is mainly based on the results of general corrosion laboratory tests, which are not strictly comparable with actual service conditions.The corrosion tables provide an initial guide to the selection of materials and are intended to facilitate understanding of the different types of corrosion damage that can arise due to poor material selection.GUIDE TO SELECTION - RyersonGUIDE TO SELECTION STAINLESS STEEL CHROME-NICKEL, NON-HARDENING, AUSTENITIC (NON-MAGNETIC) 201 (UNS S20100) An austenitic stainless steel formulated to have lower and more stable cost due to the substitution of lower cost manganese and nitrogen for a portion of the nickel found in the 300 series alloys, making this a more economical alloy.

Handling & Storage of Nitric Acid (HNO3¬) - NeoNickel

14 rows · Handling & Storage of Nitric Acid (HNO3¬) The second largest commodity mineral acid, Nitric Acid - Rolled Alloys, Inc.Type 304 L stainless is widely used in the handling and storage of nitric acid up to 60% concentration and up to the atmospheric boiling point (Figure 1 above). It has been commonly used for cooler condensers operating as hot as 200°C (390°F). The stabilized 18-8 grades, 321, and 347 are also used.Passivation Benefits for Metal Hose and Expansion Joints selection of stainless steel for handling nitric acidNitric acid is a strong oxidizing acid, so it helps to form the oxide layer on the stainless steel. Citric acid may be used instead of nitric acid for passivation, but it does not help to create the oxide layer like nitric acid does, and therefore is not as widely used.
