What is black steel? Black iron is the
uncoated steel and is also called as black steel. When steel pipe
is forged, a black oxide scale forms on its surface to give it the
finish which is seen on this type of pipe. Because steel is subject
to rust and corrosion, the factory also coats it with protective
oil. Those black steel are used for manufacturing pipe and tube,
which will not rust for a long time and requires very little
maintenance. It is sold in standard **-foot lengths TBE.
