Rolled rings

Rolled rings

Our seamless rolled rings can be forged into various configurations to suit your needs. Ranging from flat, rectangular-cross section parts to tall, cylindrical shapes, every ring delivers high strength and toughness. Seamless rolled rings are a better option when compared to castings, metal fabrications, or flame-cut plates—especially for essential applications in industries such as oil & gas, power generation, and aerospace.

BENEFITS

• Performance-wise, there is no equal for rolled rings.
• Their strength and ductility make them well suited for torque, pressure, and fatigue-resistant components.
• At FRISA, we provide the widest capabilities of any ring roller manufacturer in the world and make every ring to order. We can supply rings from one piece to high-volume orders.

PROCESS

A seamless rolled ring is made in three steps. This process directs grain flow in tangential and radial directions and provides the pieces with strength, ductility, and resistance to impact and fatigue.

• First, a preform is made on a press out of an ingot cut.
• Second, a hole is punched on the center to create a donut shape.
• Third, the preform is placed on a ring mill to expand the material to its desired dimensions.
