The journey begins by melting scrap metals and additives in an electric arc furnace (EAF), where high-power electrodes heat the metals to create a molten mixture. This process utilizes recycled steel, up to 60%, which is not only cost-effective but also environmentally considerate.

Step 2: Carbon Content Reduction

The strength and hardness of iron are enhanced by carbon, but an excess can lead to complications. Carbon content calibration is critical, employing Argon Oxygen Decarburization (AOD) or Vacuum Oxygen Decarburization (VOD) to achieve the desired levels, providing precise control over the final product’s characteristics.

Step 3: Tuning

Post-carbon reduction, the steel undergoes a balancing of temperature and chemistry to ensure consistency and adherence to the intended grade’s requirements, with adjustments made as needed based on testing and analysis.

Step 4: Forming or Casting

The molten steel is then shaped into primitive forms, such as blooms, billets, slabs, rods, and tubes, each marked for tracking through subsequent processes. These forms are then processed further depending on their final use, with some going through additional steps to acquire the necessary appearance and characteristics.

Further Processing

The steel, now in a rough shape, is subjected to hot rolling, which sets its initial dimensions. For more precision, cold rolling is employed, often necessitating further heat treatment. The annealing process follows, softening the steel and relieving stress.

Surface Treatment

Surface scale accumulation is an inevitable part of processing, affecting the steel’s appearance and properties. Descaling or pickling is essential in maintaining stainless steel’s resistance to corrosion and stain, achieved through acid baths or controlled heating and cooling.
