Frequently Asked Questions
Duplex 2205 plates supplier — what should buyers know?
A duplex 2205 plates supplier provides UNS S32205/S31803 stainless steel plate to ASTM A240/ASME SA240, typically in 3 mm to 100 mm thickness with standard widths up to 2000 mm. Buyers usually verify solution-annealed condition, EN 10204 3.1 test certificates, PMI, corrosion resistance, and plate tolerances before purchase.
What should buyers check when choosing a duplex 2205 plates supplier?
Check whether the supplier offers ASTM A240 or ASME SA240 compliant plate in UNS S32205 or S31803, with full heat traceability and EN 10204 3.1 certification. Confirm thickness, width, flatness and edge condition, plus test options such as PMI, ferrite measurement, ultrasonic testing, and corrosion-related documentation for critical service.
What sizes and specifications are common for Duplex 2205 plates?
Duplex 2205 plates are commonly supplied in 3 mm to 100 mm thickness, with standard widths around 1000, 1250, 1500, and 2000 mm, depending on mill availability. The usual specification is ASTM A240/ASME SA240 for pressure and corrosion service, with cut-to-length plates available to project dimensions and standard mill tolerances.
