Melting
The first step in the process is melting raw materials in an electric furnace. These raw materials are typically iron ore, chromium, nickel, and other elements in exact amounts.
Hot Rolling
After being heated, the billets are shaped into long, thin rods by going through a series of rolling mills. Because the metal is heated above its recrystallization temperature during this operation, it is known as hot rolling.
Pickling
The pickling process is used to the bars in order to eliminate any oxide, scale, or other surface contaminants. Usually, an acid solution is used for this.
Cutting
Lastly, shearing machines or other cutting techniques are used to cut the rods to the required length.
