09CrCuSb low alloy steel pipe advantages

Through smelting in an ultra-high power electric furnace, refining outside the furnace, and vacuum degassing, a low-alloy steel 09CrCuSb resistant to sulfuric acid dew point corrosion for seamless steel pipes, plates, forgings and special welding materials is prepared. Its characteristic is that during the corrosion process, a dense passivation film rich in Cr, Cu, Sb and Ti is formed on its surface, so it has a high anti-corrosion ability.

 

Compared with other types of steel such as low carbon steel and Corten, sulfuric acid corrosion-resistant steel has excellent corrosion resistance and mechanical properties.

Corrosion resistance
In the medium temperature and medium concentration of sulfuric acid, the 09CrCuSb alloy steel pipe is passivated due to dissolution, and a layer of passivation rich in copper, chromium, antimony and other alloying elements is formed on the surface of the steel. The chemical layer makes it highly resistant to sulfuric acid corrosion.
