The stainless steel fabricating process allows stainless steel manufacturers to produce it in a variety of parts and forms.
1. Melting
The first step involves melting raw materials together for 8-12 hours in an electric furnace.
2. Casting
Once the molten material reaches a recrystallization temperature, it continues to the next step, where it is cast into a certain form. Depending on their shape, these forms may be known as slabs, rods, blooms, billets, or tube rounds.
3. Hot Rolling
The unfinished forms are put through a hot rolling process. Slabs are formed into foil, strips, plates, and sheets, while blooms and billets are formed into coil, bars, and wire.
4. Heat Treatment and Air Hardening
In the next step, the steel is put through heat treatment and cooled through air hardening. The level of hardness of the steel depends on how long the steel is allowed to cool.
5. Cleaning
Once cooled, the steel is cleaned of buildup by way of electro cleaning or pickling.
6. Cutting
In the final step, the steel is cut to the desired shape.
7. Secondary Processing
The steel can undergo further processes such as hot rolling, cold rolling, or annealing in order to achieve a matte or shiny finish.
