With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
Selection of stainless steels for handling nitric acid (HNO3) Introduction. Nitric acid is strongly oxidising and promotes the resistance of stainless steel to corrosion. Generally stainless steels are resistant to corrosion in nitric acid. Nitric acid is used in the chemical 'passivation' of stainless steels.
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.
As noted by an ATI Metals publication, in a boiling test solution of 1% hydrochloric acid, the corrosion rate of 317 SS was 54.2 mils/year, while 316 SS corroded at a rate of 226 mils/year. 317 SS also significantly outperforms 316 SS in sulfuric acid and sodium hydroxide tests.

Our passivation formulation consists of 20% Nitric acid and 5 % sodium dichromate in water. We immerse our components in this formulation for approx. 45 min, without any heating.
Selection of stainless steels for handling sulphuric acid (H2SO4) Introduction. Sulphuric acid is oxidising when concentrated but is reducing at low and 'intermediate' concentrations. The response of most stainless steel types is that in general they are resistant at either low or high concentrations, but are attacked at intermediate ss 316 in nitric acid supplier
Differences between 316 and 316L stainless steel. 2002. A. 316 and 316L differ only by the amount on carbon in them. As I understand it, 316 L has lower carbon such that when welded the chromium carbide that forms does not deplete the chromium to the point where the corrosion of the stainless is deleteriously impacted.
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. Grade 316L is the low carbon version of SS 316. Grade SS 904L is a non-stabilised low carbon high alloy austenitic stainless ss 316 in nitric acid supplier

Nitric Acid Reaction. Stainless steels from non-stainless steels. 1. Either, place a drop of strong nitric acid on the steel surface, or the steel in acid solution at room temperature. 2. Test standard samples, such as stainless and non-stainless steel samples, in the same way.
Nitric acid is the second largest commodity mineral acid, following behind sulfuric acid. It is a strong oxidizing acid and is used in CPI processes, the production of fertilizers and explosives, and is one of the principle ingredients for pickling stainless and chromium bearing nickel alloys.
molybdenum-containing grades. One known exception is highly oxidizing acids such as nitric acid to which the molybdenum bearing stainless steels are less resistant. Types 316 and 316Ti are considerably more resistant than any of the other chromium-nickel stainless steels to solutions of sulfuric acid.
