Description
Build-to-print forged or machined component
Duplex 2205 Custom Flange to Drawing
A duplex 2205 custom flange is a build-to-print component whose forging or plate material route is selected from the drawing, service and mechanical requirements.
What is a duplex 2205 custom flange?
Nonstandard drilling, hubs, seal grooves and envelope dimensions are manufactured to the approved revision. The selected product form determines the applicable material specification.
Duplex 2205 combines high strength with resistance to chloride stress-corrosion cracking. Heat treatment, phase balance, welding and service-temperature limits need engineering control.

Dimensions, tolerances and acceptance criteria follow the standard edition and project documents named on the purchase order. Published ranges are enquiry guidance, not a pressure-temperature design approval.
Material and dimensional standards
Material specification
ASTM A182 F60 applies to UNS S32205 forgings; ASTM A240 S32205 applies to plate. The two product forms should not be described as interchangeable without approval.
Product dimensions
A custom flange is controlled by the approved drawing. Standard references apply only to the features explicitly retained in that drawing.
Typical applications and selection boundary
Applications are examples only. Confirm corrosion resistance, temperature limits, impact properties and code compliance for the actual service.

Frequently asked questions
What should be included in an RFQ for a duplex 2205 custom flange?
State the material specification, dimensional standard and edition, size, pressure class or wall thickness, end or facing detail, quantity, inspection requirements and delivery destination.
Can a duplex 2205 custom flange be supplied with EN 10204 3.1 documentation?
Yes. EN 10204 3.1 material certification and heat-number traceability can be supplied. PMI, NDE, dimensional reporting or third-party inspection should be stated on the purchase order.
Is Duplex 2205 suitable for every corrosive service?
No. Grade selection depends on the fluid chemistry, chloride level, temperature, pressure, fabrication route and governing design code. The project engineer should confirm service suitability.
