Difference Between Carbon Steel and Black Steel Compare

2018-5-17  The key 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. Black steel gets its name due to the presence of a dark-coloured iron oxide coating on the surface of the steel.
