Corrosion Resistance

Alloy 321 stainless steel plate exhibits good general corrosion resistance that is comparable to 304. It was developed for use in the chromium carbide precipitation range of 1800 – 1500°F (427 – 816°C) where un-stabilized alloys such as 304 are subject to intergranular attack.

The alloy can be used in most diluted organic acids at moderate temperatures and in pure phosphoric acid at lower temperatures and up to 10% diluted solutions at elevated temperatures. Alloy 321 resists polythionic acid stress corrosion cracking in hydrocarbon service. It can also be utilized in chloride or fluoride free caustic solutions at moderate temperatures.
Alloy 321 stainless steel plate does not perform well in chloride solutions, even in small concentrations, or in sulfuric acid service. Alloy 321 stainless steel plate can be easily welded and processed by standard shop fabrication practices.

Cold Forming

The alloy is quite ductile and forms easily.

Hot Forming

The high sulfur content of Alloy 303 also has a detrimental impact on hot workability. If hot forming is required, once again, 304 should be considered as an alternate selection.

Doshi Impex India - 304 Sheet - Stainless Steel 304 - SS 304 sheet - Stainless steel 304 sheet  - Doshi Impex Stainless Steel sheet 304 - AISI 304 - 1.4301 Sheet - UNS S30400 - Stainless steel is the most common steel. The steel contains both chromium (between 18% and 20%) and nickel (between 8% and 10.5%) metals as the main non-iron constituents. It is an austenitic stainless steel. It is less electrically and thermally conductive than carbon steel and is essentially non-magnetic. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes. 304 stainless steel has excellent resistance to a wide range of atmospheric environments and many corrosive media. It is subject to pitting and crevice corrosion in warm chloride environments and to stress corrosion cracking above about 60 °C. It is considered resistant to pitting corrosion in water with up to about 400 mg/L chlorides at ambient temperatures, reducing to about 150 mg/L at 60 °C.

304 stainless steel is also very sensitive at room temperature to the thiosulfate anions released by the oxidation of pyrite (as encountered in acid mine drainage) and can undergo severe pitting corrosion problems when in close contact with pyrite- or sulfide-rich clay materials exposed to oxidation.
304 stainless steel is used for a variety of household and industrial applications such as food handling and processing equipment, screws, machinery parts, and car headers. 304 stainless steel is also used in the architectural field for exterior accents such as water and fire features.

A Corrosion Resistant Austenitic Stainless Steel with a High Molybdenum and Nitrogen Content Developed for Use in Chloride Containing Environments. Alloy 317LMN (UNS S31726) is an austenitic chromium-nickel-molybdenum stainless steel with corrosion resistance superior to 316L and 317L. The higher molybdenum content, combined with an addition of nitrogen, provides the alloy with its enhanced corrosion resistance, especially in acidic chloride containing service. The combination of molybdenum and nitrogen also improves the alloys resistance to pitting and crevice corrosion.

The nitrogen content of Alloy 317LMN acts as a strengthening agent giving it a higher yield strength than 317L .Alloy 317LMN is also a low carbon grade which enables it to be used in the as-welded condition free from chromium carbide precipitation on the grain boundaries.

Alloy 317LMN is non-magnetic in the annealed condition. It cannot be hardened by heat treatment, only by cold working. The alloy can be easily welded and processed by standard shop fabrication practices.

Specification
Alloy 317LMN (UNS S31726)
W. Nr. 1.4439

Corrosion Resistance

The higher molybdenum and nitrogen content of Alloy 317LMN assures superior general and localized corrosion resistance in most media when compared with 304/304L, 316/316L and even 317L stainless steels. Environments that don’t attack 304/304L stainless steel will normally not corrode 317LMN. One exception, however, are strongly oxidizing acids such as nitric acid. Alloys that contain molybdenum generally do not perform as well in these environments.

Alloy 317LMN has excellent corrosion resistance in a wide range of chemicals. It resists attack in sulfuric acid, hydrochloric acid, acidic chlorine and phosphoric acid. It is used in handling hot organic and fatty acids often present in food and pharmaceutical processing applications.

Because of its low carbon content, Alloy 317LMN should be utilized when it will be exposed to temperatures in the chromium carbide precipitation range of 800-1500°F (427-816°C). The higher nitrogen content of 317LMN further retards the precipitation of sigma phase as well as carbides.

In general, austenitic stainless steels are subject to chloride stress corrosion cracking in halide service. Although 317LMN is somewhat more resistant to stress corrosion cracking than 304/304L stainless steels, because of its higher molybdenum content, it is still susceptible.

The higher chromium, molybdenum and nitrogen content of 317LMN enhance its ability to resist pitting and crevice corrosion in the presence of chlorides and other halides. The Pitting Resistance Equivalent including Nitrogen number (PREN) is a relative measure of pitting resistance. The following chart offers a comparison Alloy 317LMN and other austenitic stainless steels.

Alloy 317LMN can be easily welded and processed by standard shop fabrication practices.

Alloy 309/309S (UNS S30900/S30908) austenitic stainless steel is typically used for elevated temperature applications. Its high chromium and nickel content provides comparable corrosion resistance, superior resistance to oxidation, and the retention of a larger fraction of room temperature strength than the common austenitic Alloy 304. Alloy 309 (UNS S30900) is an austenitic stainless steel developed for use in high temperature corrosion resistance applications. The alloy resists oxidation up to 1900°F (1038°C) under non-cyclic conditions. Frequent thermal cycling reduces oxidation resistance to approximately 1850°F (1010°C). Because of its high chromium and low nickel content, Alloy 309 can be utilized in sulfur containing atmospheres up to 1832°F (1000°C). The alloy is not recommended for use in highly carburizing atmospheres since it exhibits only moderate resistance to carbon absorption. Alloy 309 can be utilized in slightly oxidizing, nitriding, cementing and thermal cycling applications, albeit, the maximum service temperature must be reduced.When heated between 1202 – 1742°F (650 – 950°C) the alloy is subject to sigma phase precipitation. A solution annealing treatment at 2012 – 2102°F (1100 – 1150°C) will restore a degree of toughness.309S (UNS S30908) is the low carbon version of the alloy. It is utilized for ease of fabrication. 309H (UNS S30909) is a high carbon modification developed for enhanced creep resistance. It most instances the grain size and carbon content of the plate can meet both the 309S and 309H requirements. Alloy 309 can be easily welded and processed by standard shop fabrication practices.

Standard
ASTM A 240
ASME SA 240
AMS 5523

Features
