Description: Type 321 Stainless Steel is a stabilized austenitic stainless steel similar to Type 304 but with a titanium addition of at least five times the carbon content. This titanium addition reduces or prevents carbide precipitation during welding and in 800 1500°F service. It also improves the elevated temperature properties of the alloy.
Topic: Re: Is 304 stainless steel pipe suitable for handling nitric acid? 13 January 2012 posed by According to "Materials Selector for Hazardous Chemicals, Vol. 5: Nitric Acid" published by MTI, much of the piping used in nitric acid applications is 304L stainless steel. 304L
Mechanism of improved corrosion resistance of type 304l stainless steel, nitric acid grade, in nitric acid environments. The NAG variety has much less susceptibility to corrosion along the long- and short-transverse directions and, therefore, less susceptibility to end grain corrosion. The means and consequences of controlling chemical composition are also discussed.

Jun 17, 2015 · 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.
Stainless steel 304/ 304l/ 304h Shims have high strength and resistance to oxidation, carburisation and other harmful effects of high temperature exposure. The high contents of nickel and chromium in the alloys also give good corrosion resistance. stainless steel 304 was the first of these alloys and it was slightly modified into Incoloy 800H.
The distinctive feature uses of 304L stainless steel 8K plate is corrosion-resistant, concentrated nitric acid and dilute nitric acid on the inherent corrosion resistance. This performance can easily make it from most other metals or alloys to be distinguished.

Jul 03, 2007 · The book, Materials Selection for the Chemical Process Industries, 2nd Edn., ISBN 1-57698-025-1, has a chapter on nitric acid. 304L stainless (UNS S30403) is frequently used. A nitric acid grade (NAG) with extremely low C, Si, P and S limits gives improved corrosion resistance, especially for the welded condition.
The corrosion resistance of three indigenous nitric acid grade (NAG) type 304L stainless steel (SS), designated as 304L1, 304L2 and 304L3 and two commercial NAG SS designated as Uranus-16 similar to 304L composition and Uranus-65 similar to type 310L SS were carried out in nitric acid media.
Hydrocloric acid Stainless generally is not recommended except when solutions are very dilute and at room tem- perature. "Mixed acids" There is usually no appreciable attack on Type 304 or 316 as long as sufficient nitric acid is present. Nitric acid Type 304L or 430 is used. Phosphoric acid Type 304 is satisfactory for storing cold phosphoric

It has guaranteed low corrosion rates and is not susceptible to intergranular corrosion (IGC) in nitric acid environments. The corrosion behavior of type 304L stainless steel, NAG, and type 304L stainless steel, commercial purity (CP), in nitric acid environments is investigated in detail.
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.
Compostions of 304L type have been used with silicon, phosphorous & sulphur limited to very low residual levels to improve the resistance in hot concentrated nitric acid. Uses for nitric acid with stainless steels. Nitric acid is widely used in the chemical 'passivation' of stainless steels. Passivation of stainless steels
SS 304H Blind Flanges are used in petroleum refining and chemical processing industry due to their excellent functioning in nitric acid and acetic acid surroundings. SS 304H Threaded Flanges are used in sour service sector because they are immune to highly
In boiling nitric acid solutions, the best results are obtained with high-chromium grades. With a chromium content of 25%, URANUS 65®, a 310L NAG (Nitric Acid modified Grade), outperforms 304L in boiling 65% acid. Its low carbon and phosphorus and its silicon
Per common passivation specifications ASTM A380 & A967, passivation is the removal of exogenous iron or iron compounds from the surface of stainless steel by means of a chemical dissolution, most typically by a treatment with an acid solution that will remove the surface contamination, but will not significantly affect the stainless steel itself.
