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 plate has good oxidation resistance in high temperature environment and can work stably below 800℃ for a long time.

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

Scope of application: 321 stainless steel sheet 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 2B finish ss sheet has a smooth, reflective surface.

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

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

4. Hairline Finish: This finish is characterized by a long, narrow line pattern and provides anti-fingerprint stainless steel 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 is 321 stainless steel?

321 stainless steel 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.

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 plate 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 plate 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 plate 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 plate 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 plate are mainly concentrated in the manufacturing industry under high temperature, high pressure and strong corrosive environment.
