Industries that Use Rolled Ring Forgings

In the metalworking industry, rolling rings mean that an ingot is passed through multiple pairs of rolls to make the thickness a more uniform one, impart a mechanical property, or reduce the overall size. This concept can be compared to that of rolling dough.

The type of rolling done is classified according to the metals and temperature used. If the heat is above the temperature for recrystallization, then it’s called hot. If it’s below the recrystallization, then it’s better known as cold rolling.

The rolls are grouped together in the mill so that a sheet can be quickly processed. There are also the rolled ring forgings that are crucial to the manufacture and design of several products. Many companies use several techniques to get the rings that they desire. The different types available can be the following:

Different Processes Used in Forging

Fire, Forge, Village Smithy, Glow, Flame

Open Die

The open die is possible when there are no precut profiles on flat dies, and they are engaged in forging. The open die design can allow the metals to go everywhere aside from the area when it comes in contact with the die. This type of forging is helpful when shaping ingots or getting an art smithing.

Closed Die

The closed die is sometimes referred to as impression die forging. It uses several molds that are attached to an anvil. A hammer is forcing the molten metals to go into the cavities. This may be a costly operation for those who are doing shorter operations, but it’s going to be a more affordable choice when there’s an increase in the number of parts produced.


Press forging includes the forming factor that’s called compression. There are many applications when it comes to press forging, and there are no limits to the products’ size that you can create with this. They can be done either cold or hot.

These rolled rings are utilized in several industries, including the nuclear sector. Read more about this sector when you click here. Others who may use them include pharmaceutical companies and machine shops.

This process begins when a circular piece of metal is pierced to make it look like a “doughnut.” The metal is then heated and rotated, so there’s a significant reduction of wall thickness, and the diameters will increase. The resulting rings can then be used in various applications in many industries.

Advantages to Know About

Cost-Effectiveness – The rings are manufactured at lower costs compared to other products. This is because as the molds are already established in the first phase, there will be lesser machining involved, and the finished shape will closely resemble the contours.

Wide Range of Materials are Used – The rings can be made with different alloys and other forgeable materials available. You can use carbon, stainless steel, and other aerospace materials in the process. The versatile factor makes them responsive and flexible. When the makers are seeking various parts and components, they can do so in-ring forging. The most common markets that utilize them are chemical, power generation, pharmaceutical, and refinery industries.

Strength – They are stronger than other parts, and they can maintain their overall strength even if there are fluctuations in temperature.

Reliability – You can rely on them when you need high temperatures for working. The higher temperature required will give them a more even grain pattern, resistance, and strength when comparing them to the other components.

They Perform Better when Heated – When you compare them to other parts, you’ll be able to predict how they will react to the heat applied to them. In other components, many users will take care of the melting point when there’s the application of heat involved. With the forgings, they can withstand the maximum heat for a very long time, so there’s no need for constant checking.

Uses of these Materials


The aviation industry understands that the parts are undergoing severe physical stress while at the aircraft. During a flight, the plane undergoes high-velocity rotations, air pressure changes, and stress. This is not to mention that a minor mechanical failure will result in catastrophic consequences.

This is one reason why the aviation industry prefers seamless rolled rings when it comes to the significant components of the craft. They are used in engines, helicopter gearboxes, and turbines. Some of their benefits include being stronger than welded parts and are lighter in general. Learn how the process is done here:


The automotive industry uses high-load components in automobiles and trucks. This is why they prefer rolled rings in clutches, camshafts, crankshafts, gears, couplings, braking systems, and more. The forged parts can handle the constant wear and tear in trucks, and they can be used daily. They are lighter and more resistant to high pressure and torque.

Production of Oil and Gas

The seamless rolled rings are known to be useful in pipe connectors in oil and gas production. Others use them in hydraulic fracturing and oil explorations. They can withstand corrosive substances and higher temperatures, and they reduce failures in an oil and gas production system.
