SS321 AISI 321 Stainless Steel Properties, TP321 321H Composition, Machinability AISI 321 stainless steel (SS321) is basically type 304 with the addition of titanium (Ti), which stabilizes carbides against sensitization to prevent intergranular precipitation of chromium carbide when the steel is heated to a temperature within the sensitization range (such as …
SUS321 and SUS347 are the basic austenitic 18/8 steel (SUS 304) stabilised by Titanium (SUS321) or Niobium (SUS347) additions. These grades are used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850°C. Grade 321 is the grade of choice for applications in the temperature
Sheath Material of SS321 Applications: Nuclear power plants, reactor instrumentation, construction of chemical instruments, such as production of acetyl acid and nitric acids, heat exchangers, annealing furnaces, paper and textile industry, crude oil refinement and petrochemistry, fat and soap industry, food processing, dairy and fermentation works.
