Standards and size range
| Standard | Covers | Size range |
|---|---|---|
| ASTM B564 | Nickel-alloy forgings | Dimensions and tolerances entirely to the order drawing; the standard sets none |
| ASTM B462 | Nickel-alloy forged flanges, fittings and valve parts for corrosive service | per standard |
| ASTM B381 | Titanium forgings | Mechanical properties guaranteed up to 1 935 mm² section; larger sections by agreement |
| ASTM A182 | Duplex and super-austenitic stainless forgings | Flanges, elbows and tees may not be machined directly from bar |
| Drawing | All forgings are made to drawing | |
These are the limits set by each standard, not our supply range; larger sizes can be supplied by agreement, with mechanical properties agreed separately.
Manufacturing and inspection
- Forged from qualified ingot or billet, then solution-annealed or annealed to the material specification.
- Tensile specimens are taken at mid-radius (mid-wall for hollow forgings), parallel to the direction of metal flow.
- Every lot is checked by PMI to confirm the alloy.
- EN 10204 3.1 certificates with every delivery; 3.2 with third-party witnessing on request.
