Uses and Purpose of 321 Stainless Steel Plates

The austenitic lineage of stainless steel includes the 321 stainless steel plates. 321 is essentially a titanium-stabilized version of 304. For applications where heat is a concern, type 321 is a suitable choice. Unlike 304, which is typically utilized up to 500 degrees Celsius, 321, however, can be used in applications up to 900 degrees Celsius. Excellent forming and welding properties can be found in grade 321. It would not be used for decorative applications because it does not polish well. Shree Venktesh Wires and Steels Pvt Limited stocks a wide range of sizes in 321 stainless steel plates certified to AMS 5510, ASTM A 240, and SA 666.

With good all-around corrosion resistance, alloy 321 (UNS S32100) is austenitic stainless steel stabilized with titanium. After being subjected to temperatures within the chromium carbide precipitation range of 800 - 1500°F (427 - 816°C), it exhibits exceptional resistance to intergranular corrosion. With higher creep and stress rupture qualities than alloys 304 and 304L, the alloy is resistant to oxidation up to 1500°F (816°C). Additionally, it is harsh in low temperatures.

How to choose 321 stainless steel plates?

321 Stainless Steel Plates are a popular choice for applications that require high temperature resistance and excellent corrosion resistance. Here are some factors to consider when choosing the right stainless steel 321 plates for your application:

  1. Corrosion resistance: 321 Stainless Steel plates are known for their excellent corrosion resistance, especially in high-temperature environments. However, depending on the operating environment, certain types of corrosion may be more prevalent.
  2. Temperature resistance: 321 Stainless Steel plates have good high-temperature resistance and are often used in applications where temperatures range from 800 to 1500°F.
  3. Mechanical properties: The mechanical properties of 321 Stainless Steel plates, such as tensile strength, yield strength, and elongation, can vary depending on the manufacturing process and composition.
  4. Fabrication requirements: 321 Stainless Steel plates can be easily formed, welded, and machined. However, the specific fabrication techniques required may vary depending on the shape and size of the plates.
  5. Cost: The cost of stainless steel 321 plates can vary depending on the supplier and quantity ordered.
  6. Supplier reputation: Choose a reputable supplier like Shree Venktesh Stainless India that offers high-quality stainless steel 321 plates and has a proven track record of delivering products on time and with excellent customer service.

Testing of Stainless Steel 321 Plates

The testing of 321 Stainless Steel plates includes intergranular corrosion testing, flaring testing, mechanical testing, micro, and macro testing, hardness testing, positive material identification (PMI) testing, etc.
