ASTM Hot Stainless Steel Plates 2b Mirror 4K No. 4 Finishing 321 201 PVC Coating Cold Rolled 0.2-3mm
Product Description
321 stainless steel, an austenitic alloy, incorporates titanium as an alloying element, heightening its resistance to intergranular corrosion, especially during welding and high-temperature processes. Its superior corrosion resistance at elevated temperatures makes it a preferred choice for applications like exhaust systems, jet engine components, and high-temperature chemical processing.
To sum up, while 304 stainless steel delivers general corrosion resistance and versatility, 321 stainless steel offers augmented resistance to intergranular corrosion and excels in high-temperature settings.
Features:
Stainless steel grades 321 and 316 both have their own advantages and are suited for different applications. Here are some advantages of grade 321 stainless steel compared to grade 316:
- High-Temperature Stability: Grade 321 stainless steel contains titanium as a stabilizing element, which helps prevent sensitization and grain boundary carbide precipitation during high-temperature exposure. This makes it more suitable for applications involving extended exposure to elevated temperatures, such as in heat exchangers and furnace components.
- Weldability: Grade 321 stainless steel has better weldability compared to 316 due to its titanium content. The titanium forms stable carbides, preventing chromium depletion at the grain boundaries during welding. This minimizes the risk of sensitization and intergranular corrosion after welding.
- Resistance to Intergranular Corrosion: The titanium content in grade 321 also contributes to its improved resistance to intergranular corrosion, especially after welding or exposure to high temperatures. This is important in applications where corrosion resistance is crucial.
- Aerospace and Jet Engine Applications: Grade 321 stainless steel is often used in aerospace and jet engine applications due to its ability to withstand high temperatures and resist corrosion in these demanding environments.
- Cost-Efficiency: Grade 321 is generally less expensive than 316 stainless steel due to its lower nickel content. This can make it a more cost-effective option for certain applications while still providing good corrosion resistance and high-temperature capabilities.

- Aerospace and Jet Engines: The high-temperature stability and resistance to sensitization make grade 321 suitable for aerospace applications, including jet engine components.
- Heat Exchangers: Grade 321 is used in heat exchangers that operate at elevated temperatures, such as those in the petrochemical and power generation industries.
- Refinery Equipment: It is used in components of refineries, especially those that come into contact with high-temperature gases and liquids.
- Food Processing Equipment: Due to its resistance to sensitization during welding and its corrosion resistance, grade 321 is used in certain food processing equipment where high temperatures are involved.

The 300 series austenitic stainless steels, comprising iron-based chromium-nickel alloys, are engineered to withstand corrosion. Their exceptional formability, wear resistance, and strength at elevated temperatures render them prevalent in piping systems. Although variations among the alloys are subtle yet intentional, they can generally be utilized interchangeably. However, optimal performance may require specific selections, as substituting in critical scenarios could lead to compromised longevity.
321 stainless steel, an austenitic alloy, incorporates titanium as an alloying element, heightening its resistance to intergranular corrosion, especially during welding and high-temperature processes. Its superior corrosion resistance at elevated temperatures makes it a preferred choice for applications like exhaust systems, jet engine components, and high-temperature chemical processing.
To sum up, while 304 stainless steel delivers general corrosion resistance and versatility, 321 stainless steel offers augmented resistance to intergranular corrosion and excels in high-temperature settings.
