Material selection
When selecting duplex plate for chloride exposure, evaluate the specific fluid, temperature and design parameters rather than relying on blanket assumptions. Fabrication typically requires qualified welding procedures and appropriate checks tailored to the intended service. Review your project requirements carefully to ensure this material aligns with your structural and operational expectations.
What to include in an enquiry
To check your quotation and identify the ordered material, include the exact UNS, finish, plate dimensions and any weld or corrosion-testing requirements.
Frequently asked questions
Why is a bare 2205 purchase description insufficient when S32205 is specified?
A bare 2205 description is insufficient because the broader 2205 designation also encompasses UNS S31803, whereas S32205 represents a distinct chemical and mechanical specification range.
