◆ 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:
Petroleum waste gas combustion pipeline
Engine exhaust pipe
Boiler shell, heat exchanger, heating furnace parts
Silencer parts for diesel engines
Boiler pressure vessel
Chemical transport vehicle
Expansion joint
Spiral welded pipes for furnace pipes and dryers
