How dual-phase structure affects fabrication
The austenitic-ferritic duplex structure is considered for combined corrosion and strength requirements. Welding and thermal processing affect that structure. Suitable procedures and final cleaning matter; fabrication practices familiar from an austenitic grade may not transfer directly.
Turn a 2205 enquiry into an exact specification
Commercial 2205 may be associated with S31803 and S32205. State the required UNS designation and product specification explicitly; availability of dual-certified material does not establish dual compliance for all 2205 stock. For shafts, assess straightness, fatigue and environment alongside strength.
Typical application areas
Pump and valve parts, chemical equipment, process plants.
