321 Stainless Steel Strip Features:

321 stainless steel strip is a Ni-Cr-Mo austenitic stainless steel material, its performance is very similar to 304 stainless steel strip.

But due to the addition of alloy titanium content, it has better resistance to grain boundary corrosion and high temperature strength. It effectively controls the formation of chromium carbide.

321 austenitic stainless steel strip has good corrosion resistance in the atmosphere and is widely used in petrochemical, electric power, bridge and automobile industries.

However, the “stainlessness” of 321 stainless steel is not absolute. Due to the special service environment, 321 stainless steel will also corrode.
Factors such as medium concentration, PH value, and temperature will have a greater impact on the corrosion resistance of 321 stainless steel.

What is the different between 321 stainless steel strip with 347 stainless steel strip?

1. Alloys 321 and 347 have similar resistance to general corrosion as the unstable Ni-Cr 304.
2. Prolonged heating in the temperature range of the chromium carbide degree may affect the corrosion resistance of alloys 321 and 347 in harsh corrosive media.
3. The corrosion resistance of the two alloys is similar in most environments; However, the corrosion resistance of the annealed alloy 321 in the strong oxidizing environment is slightly lower than that of the annealed alloy 347.
4. Alloy 347 is therefore superior in water and other low temperature environments. When exposed to the temperature range from 800°F to 1500°F (427°C to 816°C), the overall corrosion resistance of alloy 321 is much worse than that of alloy 347. Alloy 347 is primarily used for high temperature applications where strong resistance to sensitization is required to prevent intergranular corrosion at lower temperatures.

321 Stainless Steel Strip Applications:

321 stainless steel strip is applied to the field machines in the chemical, coal, and petroleum industries that require high resistance to grain boundary corrosion, heat-resistant parts for building materials and parts with difficult heat treatment.
1. Petroleum waste gas combustion pipeline
2. Engine exhaust pipe
3. Boiler shell, heat exchanger, heating furnace parts
4. Silencer parts for diesel engines
5. Boiler pressure vessel
6. Chemical transport truck
7. Expansion joint
8. Spiral welded pipes for furnace and dryers
