Overview
Forging is what you specify when the shape, the grain flow or the size rules out bar. A large diameter ring for a flange or a vessel nozzle, a disc that will be machined into a pump component, a block that will be cut into several parts — these are forged because the alternative would waste material or produce the wrong structure.
Forged material is supplied either as a near-net shape or as a rough-machined blank, depending on how much material you want to remove yourself. If you send the finished drawing we will quote the forge envelope that leaves the sensible machining allowance.
Capability range
| Product | Size range | Notes |
|---|---|---|
| Rolled ring | OD φ100 – φ1800 mm, wall ≥10 mm | Ring-rolled, supplied as-rolled or rough-machined |
| Disc / cake | φ50 – φ1500 mm | Forged and rough-machined to drawing |
| Block | per drawing | Rectangular forged block, sawn or machined |
| Bar from forged stock | φ80 – φ500 mm | See the bar & rod page |

Standards
- ASTM B381 — titanium and titanium alloy forgings. The specification that defines the grades, conditions and mechanical requirements for forged product.
- ASME SB381 / SA-381 — the ASME designation of the same specification, called up where the forged component is part of a code-stamped assembly.
- Customer drawings — dimensional and inspection requirements for the specific part.
ASTM B381 groups forgings into classes according to the quality and inspection regime applied. Which class your component needs is a question for your own engineering specification — tell us the class and we will confirm whether it can be produced, rather than assuming the highest one.
From forging to finished part
- Drawing reviewWe check the finished geometry against what can be forged and machined, and confirm the forge envelope and the machining allowance.
- ForgingThe blank is produced at the partner works by ring rolling, open-die forging or press forging as the shape requires.
- Heat treatmentAnnealing, or solution treatment and ageing where the grade and the property requirements call for it.
- Rough machiningWhere specified, the blank is rough-machined to a defined allowance so you receive a part close to finished size.
- Inspection and documentationDimensional check to drawing, MTC with heat traceability, and any additional inspection agreed in the quotation.
Order by drawing
Forged parts are quoted from drawings. DWG, DXF, STEP, IGES and PDF drawings are all workable, and a scanned or photographed drawing is enough to start a feasibility discussion. What we need alongside the drawing is the grade, the quantity, the condition, the inspection class if your specification calls one up, and any lead-time constraint.

Send the finished part drawing with the grade, quantity and condition. If your specification calls up an ASTM B381 class or a particular heat treatment, include it and the quote will be against that requirement rather than a general one.
