Black steel bars are produced in a rolling mill by a heating raw material such as blooms, billet etc at a temperature around 1200°C through a number of rolls to achieve the desired bars shape and sizes. Available shapes in the market are round, square, flat, hexagonal etc. Due to the nature of the process and temperature involved, precise control of tolerances that can be achieved in mild steel and en8 bright bars but that can be achieved in black steel bars. Therefore they are further processed to make bright steel bars for processes that require more precise accuracies. Therefore black steel bars are less expensive than mild steel bright bars.
Bright Steel Bars:
Bright Steel Bars(EN8 or Mild Steel) are produced from black bars by passing through dies in a cold condition or by turning the bars in a peeling machine and some other processes. They are used where specific tolerance is required such as for use in CNC machines, etc. Some times heat treatment such as annealing is done before cold finishing.
There are five different types of processes to achieve the desired sizes for your applications.
- Drawing
- Peeling
- Grinding
- Polishing
- Cold Rolling
