Rust and annealing skin on steel may decrease the heat transfer, can cause product contamination and may result in severe damage.
A surface treatment (internal) of carbon steel generally consists of the removal of protective coatings and grease, in a hot alkaline solution, the removal of oxides with inhibited acids and a passivation by means of phosphating or chemical passivation.
