Stainless steel is alloy steel. It is made of a mixture of iron, chromium and nickel. Stainless steel is steel with a minimum chromium content of 10.5% or higher and a maximum carbon content of less than 1.20%.

The properties of aluminum are as follows:

Thermal conductivity is good, but if you add more other materials, it will suffer from electric corrosion
And quickly lose strength above 175 ° C.
It is rarely used in process piping, however, it is used as an outer covering material for insulation to protect the insulation.

The properties of stainless steel are as follows:

Stainless steel has excellent corrosion resistance and good ductility
Due to the formation of a non-reactive chromium oxide (Cr2O3) film, which adheres closely to the metal surface, stainless steel becomes resistant to corrosion. The film acts as a barrier and protects the metal from corrosion.
Different types of stainless steel are used in industry (oil and gas, energy, electricity), such as austenite, ferrite and magnetism.
SS is used to manufacture various pipe products, such as pipes, pipe fittings and flanges.
Aluminum is the pure form of non-ferrous metals.
