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.

Applications:
- High-Temperature Environments: Grade 321 is particularly well-suited for applications involving
high temperatures, such as exhaust systems, furnace components, and
automotive parts.
- 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.
