347 / 347H Stainless Steel Bars Manufacturing Process

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.

Composition of Stainless Steel 347 / 347H Bars:

The composition of these bars includes high levels of chromium and nickel, providing the alloys with their corrosion-resistant properties. Additionally, the inclusion of columbium and tantalum enhances their ability to resist intergranular corrosion. The carbon content in SS 347H Bars is controlled to prevent sensitization during welding, maintaining the material's corrosion resistance in high-temperature applications.
