Bright steel bar is a carbon black steel which has had the surface condition improved by drawing, peeling, turning or grinding the black steel finish to produce a “bright” finish with a tighter tolerance and an improved surface without scale.High hardness and good wear resistance, when grinding, its disadvantage is that the viscosity is relatively large, and the heating up is fast, but it is easier to grind than any carbon steel, and it is much easier to cut material by hand.
