🎉 Congratulations to Iraeta Energy Equipment Co., Ltd.!
Setting a new Guinness World Record with a 21.029-meter seamless rolled ring in 2026 is a remarkable achievement.
Your continuous innovation in forging technology, commitment to quality, and ability to deliver high-performance components for the most demanding industries inspire the entire manufacturing community.
Well done, Iraeta! 👏
Forged vs Cast: Which Ring Lasts Longer?
One line on the drawing can start a long debate: “Forged or cast?”
You’re specifying large rings for a bearing, a fl**ge, or a wind turbine component. Casting can seem like the short route. But when the part carries heavy load, rotates for years, or sits in a safety-critical assembly, the choice deserves more than a price check.
Seamless rolled ring forgings are built for those conditions. Iraeta Energy Equipment Co., Ltd. is a forging specialist with production facilities in China and Spain, supplying forged components to clean energy, oil and gas, marine engineering, tunnel boring, cement production, and metal mining.
Compared with casting, a rolled ring forging offers:
- Higher strength and toughness
- Better fatigue resistance
- Finer grain structure
- No casting defects such as porosity or shrinkage
In plain language, a forged ring can take more repeated load before it fails. That is why rolled ring forgings are usually specified for high-load structural components, heavy machinery parts, and safety-critical applications.
What about cost?
The meaningful comparison is total lifecycle cost. With a longer service life, less frequent inspection, and a lower risk of sudden failure, forged rings reduce long-term operational and replacement expenses. For a ring used in a 20 MW-class offshore wind turbine or a tunnel boring machine, downtime is more expensive than the part.
Scale and control matter too.
Iraeta produces discs, rings, shells, bars, shafts, and wear-resistant grinding media — from 0.3 kg to 300 tons. Its China and Spain facilities produce seamless rings over 21 meters in diameter. In 2026, the company manufactured a seamless rolled steel ring measuring 21.029 meters, breaking its own Guinness World Record of 15.673 meters from 2022.
Raw material risk is another decision factor. Iraeta operates an in-house steel mill, supports customized material formulation, and performs full-item incoming inspection. That reduces the chance of a project stalling because of raw material supply issues.
Casting still has its place, especially for low-stress, geometrically complex parts. But if the ring carries load or is safety-critical, seamless rolled ring forgings are usually the answer.
What was the deciding factor when you compared forged rings with castings?
