Edge or end condition
- Edge or end condition is confirmed from the product form, standard and downstream fabrication need.
Testing and inspection
- Tests required by the governing purchased standard.
- PMI, NDE, corrosion, roughness or other supplementary inspection only when specified and confirmed in the quotation.
Order documents
- Inspection document type and content as ordered.
- Heat or lot traceability and supplementary reports when included in the accepted inspection plan.
Export packaging
- Export packing selected for product form, finish, dimensions, weight and transport route.
- Film, caps, interleaving, skids, cases or moisture protection only as confirmed in the order.
Why duplex for bar stock
2205 delivers a 450 MPa minimum yield — more than twice 316L — plus strong resistance to chloride pitting and stress-corrosion cracking. In seawater shafts and brine service this means smaller sections, longer life, or both. The 2205 datasheet has full chemistry, PREN and equivalents (EN 1.4462).
Machining notes
Expect roughly 20% lower cutting speeds than 316 with rigid setups and positive-rake tooling; work hardening punishes light finishing cuts. If rough-machined oversize blanks are needed, include the machining allowance and acceptance dimensions in the RFQ for route confirmation.
Quality assurance
State the required solution-annealed condition, PMI scope and acceptance criteria in the inspection plan. Ultrasonic testing to the applicable method and acceptance class is supplementary and must be requested and confirmed at quotation stage.
