Forging: a buyer's sourcing guide
Everything a procurement team should know before opening an RFQ for forging: materials, tolerances, certifications and red flags.
Recent RFQs in forging
Overview
Forging deforms hot metal under high pressure to align grain flow with the part shape, giving the highest mechanical strength of any process. Open-die suits big shafts and rings, closed-die handles series of structural parts.
When to choose this process
Choose forging when fatigue strength, impact resistance and grain integrity matter (transmission, fasteners, oil & gas).
Typical materials
- Carbon steel C45/42CrMo4
- Stainless 17-4PH
- Aluminium 6082/7075
- Titanium
- Nickel alloys
Typical tolerances
Net forging ±0.5 mm; finish-machine bearing/sealing surfaces.
Certifications to ask for
- ISO 9001
- EN 10204 3.1/3.2 mill certs
- NORSOK for O&G
Frequently asked questions
Forging vs casting?
Forging is stronger but limited in geometry; casting offers complex shapes at lower strength. For load-critical rotating parts, forge.
Minimum order quantity for closed-die forging?
Tooling makes sense above 1-2k pcs/year. Below that, open-die forging or near-net-shape casting are cheaper.
