Preset welding procedure for P-No. 10H.
Code & specification requirements
Most offshore projects which make use of duplex and superduplex stainless steels specify
requirements for a similar range of properties:
- Toughness (Charpy test).
- Ferrite and microstructure.
- Corrosion (ASTM G48A test).
- Other common weld procedure requirements, eg NDT, bend tests.
Note: Impact testing is required for nominal wall thickness ≥ 6 mm.
