Energy & Wind Power

Energy & Wind Power

 Our large-diameter forged rings are used for yaw and pitch bearings, providing the structural integrity and fatigue resistance required to withstand extreme mechanical loads. By utilizing advanced ring rolling technology, we ensure uniform grain flow and superior strength.

Oil, Gas & Petrochemical

Our forged stainless steel rings and flanges are engineered to resist severe corrosion and extreme temperatures. These components are essential for subsea equipment, valve bodies, and pressure vessel connections. Suitable grades include Duplex and Super Duplex.
