321 Stainless Steel Sheet

321 stainless steel plate is a kind of material with excellent high-
temperature Stress Rupture performance and Creep Resistance, and its stress
mechanical properties are better than those of 304 stainless steel. 321
stainless steel has good corrosion resistance in the atmosphere and is
widely used in petrochemical industry, electric power, bridges and
automobiles.

321 austenitic stainless steel has good corrosion resistance in the
atmosphere and is widely used in petrochemical industry, electric power,
bridges and automobiles. However, the "stainless" of stainless steel is not
absolute. Due to the special service environment, stainless steel will also
corrode. Factors such as medium concentration, pH value and temperature will
have great influence on the corrosion resistance of stainless steel. For
example, intergranular corrosion will occur in stainless steel when it is
used for a long time in the sensitization temperature range of 450~850℃.
The mechanism is that C combines with Cr at the grain boundary to form
Cr23C6 and precipitate, which reduces the Cr content at the grain boundary,
which is called "chromium deficiency". Cr element is one of the main
elements to inhibit intergranular corrosion. When the Cr content at the
grain boundary is less than 12%, the probability of intergranular corrosion
will increase.

Specification Of 321 Stainless Steel Sheet
Features Of 321 Stainless Steel Sheet
321 stainless steel is a stainless steel material with excellent high
temperature resistance. The following are its characteristics:

Good heat resistance: 321 stainless steel has good oxidation resistance in
high temperature environment and can work stably below 800℃ for a long
time.

Good corrosion resistance: 321 stainless steel has strong corrosion
resistance, especially in acidic environment with poor heat resistance, its
corrosion resistance is better than 304 stainless steel.

Good machinability: 321 stainless steel has good malleability, extensibility
and weldability, so it can be easily machined into various shapes.

Scope of application: 321 stainless steel is widely used in heat treatment
equipment, chemical equipment, food processing equipment, medical equipment
and other fields under high temperature environment.

What Are 321 Stainless Steel Sheets Surface Finish?
1. 2B Finish: This finish is the most commonly used and is characterized by
a smooth, reflective surface.

2. BA Finish: This is a mirror-like finish that provides high reflectivity.

3. No.4 Finish: This finish has a brushed appearance and provides a duller,
less reflective surface.

4. Hairline Finish: This finish is characterized by a long, narrow line
pattern and provides a subtle, decorative effect.

5. Embossed Finish: This finish has a textured surface with raised patterns
that create a decorative effect.

6. Etched Finish: This finish has a patterned surface created by acid
etching, providing a decorative finish.

What Are The Applications That 321 Stainless Steel Sheets Can Be Used?
321 stainless steel is a kind of heat-resistant and corrosion-resistant
stainless steel material, which is often used in the manufacturing field
under high temperature environment. Its main uses include the following
aspects:

Aviation and aerospace industry: 321 stainless steel can withstand high
temperature and high pressure environment, so it is widely used in
manufacturing missile engine parts, turbine engine parts, jet engine linings
and so on.

Chemical industry: 321 stainless steel is widely used in the manufacture of
pipelines, storage tanks, reactors and other equipment in the chemical
industry because of its excellent corrosion performance to chemicals such as
acid, alkali and salt.

Petroleum industry: 321 stainless steel has excellent high temperature
resistance and corrosion resistance, so it is also widely used in
manufacturing oil refining devices, pipelines, storage tanks and other
equipment in the petroleum industry.

Food processing industry: 321 stainless steel is widely used in
manufacturing equipment of food processing industry, such as food machinery,
kitchen utensils, etc., because it is non-toxic to food, does not produce
any peculiar smell, and is easy to clean and hygienic.

Generally speaking, the extensive application fields of 321 stainless steel
are mainly concentrated in the manufacturing industry under high
temperature, high pressure and strong corrosive environment.

There are many stainless steel products manufacturers in China, but we are
one of the best choices for you.
