Some drain cleaners wil harm plastic pipes if used excessively.
Iron rusts easily when combined with water, and drain pipes have water flowing through them. If iron was used, the pipes would rust within a few days.
The active ingredient in drain cleaners are one of a variety of compounds: caustic soda (aka lye or sodium hydroxide) being the most common, sulfuric acid is less common as it will damage metal pipes if not completely flushed out after it has done its job, etc.However the actual drain cleaner in the bottle that you buy will likely be a mixture containing other ingredients intended to make them easier to use.

The drain metal pipes are usually coated and galvanized because of the hard water.
The water goes down the plughole/drain and then down the pipes.
