Seamless Carbon Steel Pipes Black & Galvanized

seamless Carbon Steel Black Pipe. The scaly, dark-coloured ferrous oxide coating film on the surface of these pipes gives them some sort of resistance to corrosion as opposed to regular carbon steel.
 

The difference between carbon steel and black steel is that carbon steel requires galvanization because it is susceptible to corrosion whereas black steel is made from non-galvanized steel. Carbon steel gets its name due to the presence of carbon as a major constituent.
