Selection of Stainless Steel For Handling Nitric Acid HNO3
Selection of stainless steel for handling nitric acid (HNO3) The 304 types are preferable to 316 types for nitric acid applications however. This is an exception to the 'general rule' for stainless steels where the 316 types are normally found to be more corrosion resistant than 304 types.

Nitric Acid is a specific environment for intergranular attack (IGA) on sensitized austenitic grades. As such the low carbon and stabilized grades are used i.e.,304L ( instead of 304), 321 and 347. A nitric acid grade (NAG) of very low carbon, silicon and phosphorus to improve resistance to IGA is available. Molybdenum-bearing grades (316)ss 316 in nitric acid

The 304 types are preferable to 316 types for nitric acid applications however. This is an exception to the 'general rule' for stainless steels where the 316 types are normally found to be more corrosion resistant than 304 types. Over 95% concentration, aluminium alloys should be considered OR 4% silicon stainless steels.

Nitric vs. Citric Acid for Stainless Steel (SS) & Ti ...
Many people ask about the differences between nitric acid and citric acid when passivating parts made of stainless steel (SS), titanium (Ti), and other alloys. In the past, manufacturers avoided citric acid due to potential organic growth and molding issues.
Passivating Stainless Steel with Nitric or Citric Acid ...
Manufacturers of SS pots, cookware and other stainless steel products use a hot nitric acid bath to passivate the SS. I can get nitric acid but it's nasty stuff and it has to be used in a certain way or it can ruin your stainless, on the other hand citric acid is said to not attack the SS but only remove any iron from the surface and after ss 316 in nitric acid

Use of stainless steels in contact with battery acid. Battery Acid is sulphuric acid with a weight percentage concentration of over 35 i.e. at a 'fully charged' specific gravity of 1.28. The selection of 304 or 316 types for applications involving prolonged contact, such as storage tanks, is not advisable.
Using Acids With Stainless Steel
In July 1996, the laboratory supervisor at a major stainless steel processing facility sustained a severe eye injury when a mixture of 25ml concentrated hydrochloric acid, 25ml concentrated nitric acid and 50ml iso-propyl alcohol burst through the top of the storage bottle and splashed into his right eye.
How To Passivate Stainless Steel Parts - mmsonline.com
After thorough cleaning, the stainless steel part is ready for immersion in a passivating acid bath. Any one of three approaches can be usednitric acid passivation, nitric acid with sodium dichromate passivation and citric acid passivation. Which approach to use depends on the grade of stainless steel and prescribed acceptance criteria.
Effects of nitric acid passivation on the pitting ...
Samples of 316 stainless steel have been subjected to passivation treatments at ambient temperature for 1 h in solutions of up to 50 wt% nitric acid. Pitting potentials of the treated samples were measured in 1 M NaCl at 70C and were shown to vary with the concentration of the pre-treatment; increasing with concentration up to 25 wt% and then ss 316 in nitric acid

Nitric Acid Resistant Materials - Waverley Brownall
Nitric Acid: Stainless Steel Exception For nitric acid, stainless steel 304 is often used in a replacement for 316, which is the opposite solution for most corrosion resistant tactics (for nitric.) The British Stainless Steel Association recommends for over 95% concentration that aluminium alloys can be considered.
Sustainability Of SS 904L VS SS 316
Grade SS 316 is the standard molybdenum-bearing grade. The molybdenum gives Grade SS 316 high corrosion resistant properties and particularly high resistance to pitting and crevice corrosion in chloride environments.
