The main component of both carbon steel and stainless steel is iron; then why can’t carbon steel be pickled?

Both carbon steel and stainless steel consist mainly of iron, so why can’t carbon steel be pickled?
Stainless steel pickling can form a dense oxide film on the surface, preventing the interior materials from oxidizing. Carbon steel does not have this capability.
The main component of stainless steel is not iron; in fact, it does not contain any iron at all.
Carbon steel can also be pickled; steam pipes are made of carbon steel, and if they need to be clean before being put into use, pickling is required
Carbon steel is pickled primarily to remove rust from the inner walls of pipes, thereby reducing the time required for steam purging. Stainless steel is pickled mainly on its welds to form a dense oxide layer that prevents the welds from oxidizing

You’re just talking nonsense without any basis. Stainless steel is an alloy of iron to which other elements such as Cr and Ni are added; without iron, it cannot be called steel
Carbon steel is pickled primarily to remove rust from the inner walls of pipes and reduce the time required for steam purging, while stainless steel is pickled mainly on its welds to form a dense oxide film
Then why doesn’t a magnet attract stainless steel pipes?
Carbon steel steam pipes are generally purged with steam; acid cleaning is not used, as it increases corrosion.
