321 SS is a titanium stabilized austenitic chromium-nickel stainless steel which was developed to offer an 18-eight type alloy with improved intergranular-corrosion resistance. 321 chrome steel must be thought-about for applications requiring intermittent heating between 800ºF (427ºC) and 1650ºF (899ºC), or for welding underneath conditions which stop a post-weld anneal. We at Naadishwar Steel are supplier and provider of Stainless Steel h Sheets Plates in Indian in addition to worldwide market. We manufacture chrome steel sheets and plates in customize design utilizing premium quality uncooked materials. We have an professional group that does their work in a correct method and produce a excessive-high quality product in terms of usability, reliability, and longevity.
The mechanical properties of grade 321 Stainless Steel sheet are displayed in the following table. Matching filler metals can be found for welding Type 321 stabilized stainless-steel.
Grades 321 and 347 are the essential austenitic 18/eight steel (Grade 304) stabilised by Titanium or Niobium additions. These grades are used as a result of they don’t seem to be sensitive to intergranular corrosion after heating inside the carbide precipitation range of °C. Grade 321 is the grade of alternative for applications within the temperature vary of up to about 900°C, combining excessive energy, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion. Stainless Steel Shee/Plate 321 is generally used for aerospace, thermal, electrical, and structural purposes. 321 stainless is strengthened with titanium, this alloy excels in high temperature environments, offering resistance to cracking and corrosion.
- In addition to wonderful corrosion resistance and strength properties, these Stainless Steel 321 Din 1.4541 Sheets Plates additionally present the wonderful fabricability and formability which are typical of the austenitic stainless steels.
- 321 Stainless Steel Sheet is a titanium stabilized austenitic chromium-nickel chrome steel which was developed to offer an 18-8 sort alloy with improved intergranular-corrosion resistance.
- These SS 321 UNS S32100 Sheets Plates also offer larger creep, stress-to-rupture and tensile strength at elevated temperature.
- Since titanium has a stronger affinity for carbon than chromium, titanium carbide precipitates inside the grains as a substitute of forming at the grain boundaries.
- This materials is stabilized towards chromium carbide formation by the addition of titanium.

Generally, 100 ppm chloride in aqueous environments is taken into account to be the limit for both the unstabilized and the stabilized alloys, significantly if crevices are present. Higher ranges of chloride ion may cause crevice corrosion and pitting. For extra extreme conditions of upper chloride stage, lower pH and/or larger temperature, alloys with molybdenum, similar to Type 316, ought to be thought of. The stabilized Type 321 alloy passes the a hundred hour, 5% neutral salt spray check (ASTM-B-117) with no rusting or staining of samples. However, exposure of those alloys to salt mists from the ocean could be anticipated to cause pitting and crevice corrosion accompanied by severe discoloration.
We provide 321 stainless steel sheet in quite a lot of lengths and widths and might custom reduce to your precise specs. AISI/SS 321 Sheet is stabilized chrome steel that offers varied benefits and has glorious corrosion resistance. It is employed for manufacturing numerous products for the prolonged services at a temperate of 800 diploma F to 1500 degree F. It is also considered best for prime-temperature services due to its wonderful mechanical properties.
Type 321 chrome steel provides greater creep and stress rupture properties than Type 304 and, significantly, Type 304L which could even be thought of for exposures the place sensitization and intergranular corrosion are issues. This ends in greater elevated temperature allowable stresses for this stabilized alloy for ASME Boiler and stress Vessel Code purposes. The Type 321 alloy has a maximum use temperature of 1500°F (816° C) for code applications like Type 304, whereas Type 304L is proscribed to 800° F (426° C). You should buy this product from our dealer as per your desired dimensions. The resistance of the stabilized Type 321 alloy to pitting and crevice corrosion within the presence of chloride ion is similar to that of Type 304 or Type 304L stainless steels due to similar chromium content.
The Type 321 alloy is not recommended for publicity to marine environments. Organic media or weakly corrosive aqueous agents, mil and different dairy merchandise, or atmospheric conditions rarely produce intergranular corrosion even when massive amounts of precipitated carbides are current. When skinny gauge materials is welded the time within the temperature vary of 800 to 1500° F (427 to 816° C) is so brief that with most corroding media the unstabilized sort materials is mostly satisfactory. The extent to which carbide precipitation could also be harmful depends upon the length of time the alloy was uncovered to 800 to 1500° F (427 to 816° C) and upon the corrosive setting. Even the longer heating times concerned in welding heavy gauges are not dangerous to the unstabilized “L” grade alloys where the carbon content is saved to low quantities of zero.03% or less.
