This process can develop a deep black oxide over the surface of the steel.
Black steel sheet density.
For kg m 3 multiply density in lb in.
It is used to add mild corrosion resistance for appearance and to minimize light reflection.
It is easily cut and machined and is a good material to practice welding on.
Because bright mild steel is cold rolled it is accurate in size whereas black mild steel is not as accurate.
To achieve maximal corrosion resistance the black oxide must be impregnated with oil or wax.
Hope it is of help to you.
Black oxide or blackening is a conversion coating for ferrous materials stainless steel copper and copper based alloys zinc powdered metals and silver solder.
Black mild steel has a dark blue oily surface and bright mild steel has a silvery grey surface.
The table below lists out the density values of common metals and alloys including iron carbon steel steel wire alloy steel bearing steel stainless steel copper brass bronze aluminum magnesium nickel zinc lead etc.
One such method to achieve these tones is by dipping it in a heated chemical bath.
One of its advantages over other coatings is.
Oxides produced by this alkali method are weak and prone to abrasion if not protected with waxes or oils.

For g cm 3 multiply density in lb in.
Black steel gets its name due to the presence of a dark coloured iron oxide coating on the surface of the steel.

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.
Mild steel is reasonably soft and ductile.
The density of steel is in the range of 7 75 and 8 05 g cm 3 7750 and 8050 kg m 3 or 0 280 and 0 291 lb in 3 the theoretical density of mild steel low carbon steel is about 7 87 g cm 3 0 284 lb in 3.
For density in lb ft 3 multiply lb in.
