Both nitric acid and citric acid are effective in passivating many grades of stainless steel, and both methods are described in detail in the industry standards ASTM A967 and AMS 2700. Passivation of titanium, however, is typically governed by ASTM F86 which only specifies nitric acid and not citric acid.Nitric acid Sandvik Materials TechnologyNitric acid, HNO 3; Conc. % 20 30 30 30 30 50 50 50 50 50 60 60 60 60 65 65; Temp. °C 120 20 70 106 =BP 120 20 70 90 110 117 =BP 20 60 100 121 =BP 20 60; Grade or type of alloy: Carbon steel

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 Nitric Acid - Rolled Alloys, Inc.This grade can be useful at concentrations above 70%. In addition to attacking chromium depleted regions due to carbide precipitation, nitric acid can also attack sigma phase or other transitional phases in molybdenum bearing alloys. As a result, molybdenum bearing grades, such as 316/L, are not particularly useful in nitric acid service.

Is there passivation in stainless steel?

Since the main constituent of stainless steel is iron, passivation is required to gain the full potential of its corrosion resistance. This process was traditionally done with nitric acid, but recently introduced citric acid processes show many benefits and have rapidly gained popularity.See all results for this questionIs there nitric acid in stainless steel?Generally stainless steel are resistant to corrosion in nitric acid. Nitric acid is used in the chemical passivation of stainless steel. Commercially concentrated acid is around 65 wt % (sg = 1.40). Higher concentrations obtained by removing water, which can involve the use of sulphuric acid, which has a high affinity for water.See all results for this questionIs stainless steel resistant to corrosion?Generally stainless steel are resistant to corrosion in nitric acid over a wide range of concentration and temperature.
