Manufacturing Process Of Super Duplex S32760 Bars


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.


After melting, the metal is put into molds to form slabs or billets. The processing of these first forms is then continued.

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.


After that, the rods are annealed to reduce stress and enhance machinability. In order to do this, the rods must first be heated to a certain temperature and then gradually cooled.


Lastly, shearing machines or other cutting techniques are used to cut the rods to the required length.
