Do you need parts for your flanges? Are you trying to work on a pressure vessel connections forging projects? If your answer is yes to these questions, you’ll need to know more about seamless rolled ring forgings that are made of steel because they’re perfect for both situations.

How Forged Steel Rings are Made

The process of manufacturing seamless rolled ring forgings starts with a circular piece of metal that’s been cut to the required weight before being rounded out. Through the open die forging process, the circular metal is then pierced at the center to produce a hollow shape of a doughnut. Before it is placed on the mandrel or the idler roll, it needs to be heated above recrystallization temperature which is usually between 400 and 700˚C.

The Next Steps

Once the heated metal is on the roll, the walls of the doughnut are pushed outward in order to reduce the thickness of its walls and increase the steel ring’s diameters. In case you’re wondering, the roll has the capacity to produce a wide array of shapes as well as proportions. In most cases, seamless rolled ring forgings that are made of steel have a thickness-to-height ratio between 1:16 and 16:1.

What are the Properties of Seamless Rolled Ring Forgings?

Seamless rolled ring forgings are known for their higher strength and resistance because the steel’s grain pattern is significantly improved by the recrystallization process. Furthermore, these forged steel rings are also durable because their ability to resist deforming from heat allows them to maintain their shape even when they’re subjected to drastic temperature fluctuations. Also, seamless rolled ring forgings are cost-effective because they require less machining, raw materials, and labor compared to similar components because the steel ring’s shape doesn’t change much during the entire duration of the manufacturing process.
