Rings · Discs · Shafts · Blocks · Custom Envelopes
Align the forging specification and revision, F-Grade or UNS, starting stock, envelope, heat treatment, machining allowance, test coupons, mechanical testing, NDE, documentation and quantity before comparing quotations.
Before requesting a quote: distinguish the forging from its starting billet and from the final machined part. Freeze the rough envelope, delivery condition, allowance, tests, NDE stage and machining responsibility. “Forged titanium” alone is not a complete order.

Standards Map
| Reference | What it can control | What it does not replace |
|---|---|---|
| ASTM B381 | Annealed titanium and titanium-alloy forgings by applicable F-Grade, chemistry and mechanical-property requirements. | Customer drawing, custom route, machining allowance, optional NDE or final-part acceptance. |
| ASTM B348/B348M | Annealed titanium and titanium-alloy bar and billet within its scope. | It does not convert bar/billet into a forging or define the forging envelope. |
| ASTM E2375 or project NDE procedure | Ultrasonic examination of wrought products when appropriately invoked and supplemented. | The purchase order must still state class, coverage, geometry, stage and acceptance. |
| Final-part drawing | Machined geometry, GD&T, surface, interfaces and final inspection. | Forging-process and lot evidence unless explicitly connected in the order. |
A generic equipment list does not prove part capability. A forging basis does.
25 MN (approx. 2,550 tonne-force) fast-forging hydraulic press, installed 2019, in our own plant.
Billet from our own mill. The heat is traceable from melt through to the delivered forging, which is not the case when the forger buys billet on the open market.
Flange forgings, including flange rings, are forged entirely in-house. The ring is not bought in and re-machined.
Ring, disc, shaft, block, sleeve and near-shape flange forgings.
The size envelope is confirmed against your part rather than published as a single maximum, because press capacity limits the projected area under the dies per stroke — not the finished part size. A long shaft cogged under narrow dies and a full-face upset disc sit at completely different points of the same press capacity, and a single "maximum diameter" figure would misrepresent both.
ASTM B381 F-grades, ordered by F-number and UNS rather than by the loose "Grade" shorthand — F-5 is UNS R56400 and F-23 is UNS R56407, which is not the same material as the F136 implant grade R56401.
Everything above is a basis, not a quotation. Whether your part fits depends on section changes, reduction, orientation and the machining plan, which is what the review below is for.
Process Review
The order-specific route is confirmed after final-part, envelope, material, quantity, testing and machining review. A generic equipment list does not prove part capability.
Freeze final drawing, envelope, F-Grade, route assumptions, tests and exceptions.
Link starting heat/lot, heating, deformation sequence, orientation and intermediate controls.
Control condition, coupons, scale removal, rough machining and inspection surfaces.
Perform ordered tests at agreed stages and link reports to the shipped forging/lot.
Applications
Control approved specification, source, orientation, heat treatment, coupons, mechanical tests, NDE, machining and customer qualification.

Inspection & Evidence
ASTM B381 states that nondestructive requirements such as ultrasonic, X-ray or surface inspection are specified by the purchaser when required. Write the method, procedure, class or acceptance criteria, coverage, surface/geometry condition, inspection stage, personnel qualification and report into the order.
A clean report name is not enough. The result must link to the correct forging, heat/lot, drawing, revision and delivered condition.
Purchase Guard
Freeze the specification, F-Grade, starting stock, envelope, route, orientation, heat treatment, coupons, allowance, machining scope, tests, NDE, traceability, change control and commercial basis.
FAQ
Provide the final-part drawing and forging-envelope drawing if available, ASTM B381 or other specification and revision, F-Grade or alloy/UNS, forging type, rough dimensions, heat-treatment condition, machining allowance, quantity, test-coupon requirements, mechanical testing, NDE, inspection, documentation and delivery condition.
A forging is shaped by a defined forging route and ordered as a forging specification or customer-controlled product. Bar or billet may be starting stock controlled by a different material specification such as ASTM B348/B348M. The terms should not be interchanged without an approved order basis.
Not necessarily. ASTM B381 states that nondestructive requirements such as ultrasonic, X-ray or surface inspection are to be specified by the purchaser if required. Method, acceptance class, extent, timing and report must be written into the order.
Allowance depends on forging route, scale and surface removal, alpha-case depth where the heating route produces one, distortion, heat treatment, datum strategy, inspection stock and finish-machining plan.
No universal percentage or superiority claim is valid. Performance depends on alloy, starting stock, reduction and deformation route, temperature, heat treatment, section size, orientation, microstructure, sampling, final geometry and service load.
No. Application labels do not define material, approved source, process qualification, inspection, traceability or regulatory/customer approval. The buyer must provide the governing drawing and project requirements.
Unknown items can remain open for review. Mark mandatory requirements and permitted supplier proposals so route, exceptions and evidence can be addressed before quotation.
