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):
- 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.
- 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.
- 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.
- Heating: Heat the material to a temperature range of 450°C to 800°C (842°F to 1472°F).
- Soaking: Maintain the temperature for a sufficient time to relieve residual stresses without significantly affecting the material’s properties.
- 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.

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.
