321 Stainless Steel Pipe Data Sheet

General Description:

321 Stainless Steel Pipe, also known as UNS S32100 and Grade 321, principally 17% to 19% Chromium, 12% Nickel, 0.25% to 1% Silicon, up to 2% Manganese, traces of Phosphorus and Sulfur, 5 x (c + n ) .70% titanium, balance iron. In terms of corrosion resistance, 321 is equivalent to Grade 304 in the annealed condition and is superior if the application involves use in the 797°F to 1652°F range. Grade 321 combines high strength, scale resistance, and phase stability with resistance to subsequent aqueous corrosion.

Magnetic PropertiesAustenitic stainless steels like 321 are generally non-magnetic in the annealed condition. However, they can become slightly magnetic after cold working or exposure to certain environments.

Corrosion Resistance:

321 stainless steel offers excellent corrosion resistance in various environments, especially in applications involving exposure to mild to moderate concentrations of oxidizing agents. Its resistance to intergranular corrosion after exposure to elevated temperatures makes it a suitable choice for specific applications. Here are some key points:

  • Oxidation Resistance: 321 stainless steel performs well in high-temperature environments due to its chromium and nickel content. It forms a stable oxide layer on the surface that protects against oxidation at elevated temperatures.
  • Intergranular Corrosion Resistance: The addition of titanium to the alloy composition helps prevent the formation of chromium carbides at grain boundaries, making 321 stainless steel resistant to intergranular corrosion after exposure to high temperatures. This property makes it particularly useful in applications where welding or exposure to elevated temperatures might occur.
  • Sensitization: Sensitization is the formation of chromium carbides at grain boundaries, which can reduce the material’s corrosion resistance. 321 stainless steel’s composition minimizes the risk of sensitization, enhancing its performance in corrosive environments.
  • Applications: Due to its corrosion resistance properties, 321 stainless steel is used in industries such as aerospace, chemical processing, automotive, high-temperature processing, oil and gas, food and beverage, and more.
  • Limitations: While 321 stainless steel is suitable for a wide range of environments, it might not be the best choice for highly acidic or chloride-rich environments where more corrosion-resistant stainless steel grades, such as 316 or 904L, might be preferred.

It’s important to consider the specific corrosive environment and application requirements when selecting a stainless steel grade. Always refer to the manufacturer’s datasheets or consult with materials experts to ensure the appropriate material choice for your intended use.
