What is Ring rolling / forging?

Ring rolling / forging capability for titanium components

Hydraulic and mechanical press capability for Ring rolling / forging, with induction heating, die temperature control, and grain flow optimization.

Engineering Parameters & Capabilities

Closed-die forging of titanium uses shaped dies to compress heated billet into a net-shape or near-net-shape component. The process aligns grain flow with the component contour, producing superior mechanical properties compared to machined-from-bar stock, specifically for ring. Precision ring for General, Aerospace present unique challenges: Roundness tolerance ±0.01 mm on large diameter rings (> 300 mm). Heat treatment distortion management.

Parameter Specification
Method Closed-die / open-die / isothermal
Temperature 850–1050°C (below beta transus)
Grain Flow Aligned with component contour

Frequently Asked Questions

What titanium grades are suitable for Ring rolling / forging?
Ring rolling / forging can be performed on Grade 1, Grade 2, Grade 5 (Ti-6Al-4V), Grade 7, and other grades. The specific grade selection depends on the required mechanical properties, corrosion resistance, and end-use application requirements.
What tolerances can be achieved with Ring rolling / forging?
Typical achievable tolerances for Ring rolling / forging are +1.0 mm (as-forged) / +0.05 mm (post-CNC). Tighter tolerances may be possible depending on part geometry, material condition, and quantity. Our engineering team reviews each project to determine the optimal tolerance-cost balance.
What quality certifications apply to Ring rolling / forging?
All Ring rolling / forging operations are performed under ISO 9001:2015 — Quality Management System, AS9100D — Aerospace Quality Management, ASTM B265 — Titanium Strip, Sheet, and Plate Standard certified quality management systems. Full traceability documentation, material certifications (EN 10204 3.1), and inspection reports are provided with each shipment.
What is the typical lead time for Ring rolling / forging projects?
Lead times for Ring rolling / forging vary by complexity and quantity. Prototype quantities (1-10 units) can typically be completed in 3-7 business days. Production quantities require 15-25 business days. Rush orders are available for qualifying projects. Contact our sales team for a specific timeline.
