H type corten finned tube is H type finned tube and the bare tubes are Corten steel tube.

Corden steel tube is divided into two categories: corten A and corten B. It is the representative steel of Cu-P series steel in the United States. It is a low-alloy high-strength atmospheric corrosion resistant structural steel.

H type corten finned tube is mainly used for economizing gas, air preheater, heat exchanger and evaporator in high sulfur flue gas to resist dew corrosion of sulfur flue gas. It has excellent resistance to sulfur ion, hydrochloric acid and other acid corrosion.
