Heat Treatment

321 stainless steel is typically heat treated to enhance its mechanical properties and achieve the desired balance of strength and corrosion resistance. The heat treatment process for 321 stainless steel usually involves annealing and/or solution annealing. Here’s an overview of the typical heat treatment process:

Annealing (Solution Annealing):
  1. Heating: Heat the material to a temperature range of 950°C to 1050°C (1742°F to 1922°F) for a sufficient time to ensure uniformity throughout the material.
  2. Soaking: Hold the material at an elevated temperature for a period of time to allow for the complete dissolution of any carbides or other precipitates.
  3. Cooling: Rapidly quench the material in water or air to room temperature. This process prevents the formation of harmful phases and ensures the material remains in the austenitic phase.

The purpose of annealing is to restore the material’s corrosion resistance and ductility while minimizing the formation of chromium carbides that can lead to intergranular corrosion.

Stress Relief Annealing:

For parts that have undergone extensive forming, welding, or machining, a stress-relief annealing process can be applied.

  1. Heating: Heat the material to a temperature range of 450°C to 800°C (842°F to 1472°F).
  2. Soaking: Maintain the temperature for a sufficient time to relieve residual stresses without significantly affecting the material’s properties.
  3. Cooling: Air cooling or furnace cooling to room temperature.

Stress relief annealing helps to reduce internal stresses that might have developed during processing.

It’s important to note that specific heat treatment parameters can vary based on the material’s thickness, geometry, and intended application. Always consult the manufacturer’s guidelines or relevant industry standards for precise heat treatment instructions for 321 stainless steel.

  1. Aerospace Industry: Parts and components for aircraft engines and exhaust systems due to the alloy’s ability to withstand high temperatures and corrosive environments.
  2. Chemical Processing: Equipment such as reactors, columns, and pipes in chemical processing plants where resistance to corrosive chemicals and high-temperature oxidation is crucial.
  3. Oil and Gas Industry: Used in offshore platforms, pipelines, and equipment exposed to corrosive seawater and high-temperature conditions.
  4. Heat Exchangers: Used in the fabrication of heat exchanger tubes and plates that require resistance to both high temperatures and corrosive fluids.
  5. Automotive Exhaust Systems: Exhaust manifolds and catalytic converters where high-temperature oxidation resistance and durability are important.
  6. Food and Beverage Industry: Parts of processing equipment, tanks, and piping systems that require corrosion resistance in acidic or chloride-rich environments.
  7. Medical Equipment: Some medical devices and equipment require stainless steel with good corrosion resistance for sterilization processes.
  8. Welded Components: 321 stainless steel’s resistance to intergranular corrosion makes it suitable for welded structures that might be exposed to corrosive environments.
  9. Furnace Parts: Used in industrial furnaces and ovens where high-temperature oxidation resistance is essential.
  10. Construction and Architecture: Decorative elements, exterior cladding, and structural components where a combination of aesthetics and corrosion resistance is desired.
  11. Power Generation: Components in power plants, including boiler tubes and high-temperature piping, where corrosion resistance and thermal stability are critical.
  12. Pulp and Paper Industry: Used in equipment like digesters, bleachers, and evaporators where resistance to corrosive chemicals and high temperatures is needed.

It’s important to note that the suitability of 321 stainless steel for a specific application depends on factors such as the nature of the environment, temperature, mechanical loads, and more.

Package of 321 Stainless Steel Sheet

When exporting 321 stainless steel plates, it is necessary to ensure that the material is properly protected from damage during transportation. The following are the export packages of stainless steel plates commonly used by our company.

wooden frame, waterproof paper, angle steel

Steel frame: Fix the stainless steel sheet around the steel frame. These sheets are stacked and secured with metal straps. Steel frame provides extra protection during transport.

It is important that information such as material type, size, weight, and any handling instructions are clearly marked on the packaging. This will help ensure that materials are properly handled in transit and arrive at their destination intact.

The conventional export packaging is as follows. If customers need other packaging methods, we are very happy to cooperate and look forward to cooperating with you.

321 VS 347 Stainless Steel

  • The primary difference between 321 and 347 stainless steel is the stabilizing element they use (titanium vs. niobium) to prevent sensitization and intergranular corrosion.
  • 347 stainless steel is generally considered more effective in preventing sensitization in high-temperature applications.
  • Both alloys have similar mechanical properties, with some differences due to the presence of niobium in 347 stainless steel.

When choosing between 321 and 347 stainless steel for a specific application, it’s important to consider factors like temperature, corrosion resistance requirements, and potential exposure to sensitization. Consulting with stainless steel suppliers or referring to relevant industry standards can help ensure the best choice for your specific needs.
