Manufacturing Processes: How the “Black” Bar is Made
Choosing the right Stainless Steel Black Round Bar In Tripura starts with understanding how it is manufactured.
Hot Rolling (The Raw Finish)
- Stainless steel billets are heated above 1100°C.
- The heated billets pass through rolling mills to achieve the required diameter.
- During cooling, oxygen reacts with the surface.
- This forms a dark iron oxide layer called mill scale, giving the bar its natural black finish.
Chemical Blackening (The Aesthetic Finish)
- Machined or cold-drawn bars undergo chemical treatment.
- Bars are immersed in a heated solution of sodium hydroxide, nitrates, and nitrites at around 140°C.
- This creates a thin layer of magnetite (Fe₃O₄).
- Produces an attractive matte black appearance without changing dimensions.
