Using Protective Coatings in Heat Treatment | 2012-05-02 steel pipe for green house use Heat treatment
When steel is heated in an open furnace in the presence of air or products of combustion, two surface phenomena take place: oxidation and decarburization. The oxidation of steel is caused by the presence of oxygen, carbon dioxide and/or water vapor. The oxidation may manifest itself in a range from a tight, adherent straw-colored film that forms at a temperature of about 180°C (lower temperatures) to a loose, blue-black oxidSee more on forgemag steel pipe for green house use Heat treatmentThe heat treatment of carbon steel pipe, Carbon steel pipe steel pipe for green house use Heat treatmentHeat treatment purposes for steel pipe.
