Duplex 2205 Plates - Supplier, Stockist & Exporter in Mumbai

Grade data, forms and enquiry details for Duplex 2205 plates.

Catalogue context: Metalex’s 2022 sheet/plate/coil range spans 1,250–2,500 mm width, up to 6,000 mm length and 0.1–50 mm thickness across all flat forms; this is not a grade- or form-specific stock guarantee. Confirm the actual offered size, finish and certificate.

Duplex 2205 plates are available for enquiry as stainless steel flat products. A duplex stainless steel combining higher strength than common austenitic grades with improved resistance to chloride stress corrosion cracking. This grade is specified by its material standard and UNS designation; the right finish and tolerance depend on fabrication and service conditions.

For duplex 2205 plates, send thickness, width and length, grade designation (S32205 or S31803), finish, quantity and destination. Confirm size and testing requirements before ordering; weld procedures and grade substitution require engineering review.

What these numbers mean for a buyer

The chemistry row shows a published typical production example, not min/max acceptance ranges. The mechanical row shows minimum values from the cited ASTM A240 summary, not guaranteed results for any individual coil or plate. Review the exact heat number and measured results on the supplied EN 10204 3.1 mill certificate. UNS identifies the alloy; thickness, finish and dimensional tolerances must still be specified separately.

Practical ordering checklist

Material grade and UNS, plus whether dual certification is required.
ASTM/ASME or EN standard and revision required by the project.
Thickness, width and cut length, plus tolerances and edge condition.
Finish, quantity, delivery destination and packing requirements.
MTC, inspection, surface testing and any project-specific corrosion test.

Forms and finishes

Plates are flat-rolled forms, but ordering dimensions and feasible finishes vary by thickness, route and grade. Confirm the requested finish, tolerances and certificate for this specific plate before quoting.

Typical applications

Chemical processing, marine systems, heat exchangers and demanding fabrication. Engineering selection must account for the actual fluid, temperature, environment and code.
