CORROSION OF 20# STEEL IN HCl-H₂O-CMS SYSTEM

Effects of HCl-H2O-CMS system on corrosion of 20# steel was studied by using corrosion field data in the process of methane chlorination production.The main influecing factors of 20# steel corrosion in HCl-H2O-CMS system were the content of hydrochloric acid and water.Corrosion rate equation was also obtained by fitting corrosion field data.According to corrosion feature of 20# steel in this system,the process,structure and materials were improved.
