Application:

 

321 stainless steel coil is a derivative of 304 stainless steel, and there is not much difference in corrosion resistance.However, under the heat-resistant working conditions of 500-600 degrees Celsius, 321 grade stainless steel coils are mostly used.

It is because 321 steel coil has titanium as a stabilizing element, which effectively controls the formation of chromium carbide.

At the same time, 321 stainless steel is also a heat-strength steel, which makes it have better resistance to intergranular corrosion and high-temperature strength, so it can be used to manufacture linings and pipelines for wear-resistant acid containers and wear-resistant equipment.
 

Application range of 321 stainless steel coil:

 

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 vehicle.

7. Expansion joint.

8. Spiral welded pipes for furnace pipes and dryers.
