Duplex stainless steel products
Request S32205 Duplex Steel Bar with the required standard, dimensions, tolerance, finish, inspection and mill test certificates from SAKY METAL.
Technical procurement data
Standards, supply and inspection
S32205 Duplex Steel Bar UNS S32205 duplex bar combines austenitic-ferritic corrosion resistance with higher strength than conventional 300-series stainless steel. Procurement should control heat treatment, ferrite balance and traceability because these directly affect welding and chloride service performance.
| Material / grade | UNS S32205 / EN 1.4462; S31803 may be considered only when the project specification permits the chemistry range. |
|---|---|
| Product form | Bar |
| Standards and order reference | Common references are ASTM A276 or ASTM A479 with ASTM A484/A484M general requirements; project-specific NORSOK or purchaser requirements can be added. |
| Dimensions and tolerances | Round, square or flat bar dimensions, length, straightness and machining allowance are supplied to the stated ASTM/EN tolerance or customer drawing. |
| Surface and supply condition | Hot finished, solution annealed and pickled, peeled, ground or polished depending on machining and corrosion requirements. |
| Inspection options | PMI, ferrite measurement, dimensional inspection and ultrasonic testing can be specified; corrosion testing is performed only when required by the order. |
| MTC and traceability | EN 10204 3.1 MTC with heat chemistry, mechanical properties and heat-treatment record; third-party inspection can be arranged. |
| Typical applications | Marine shafts, chemical-processing components, pump and valve parts, desalination equipment and oil-and-gas hardware. |
| RFQ checklist | Send the bar grade and standard, required dimensions and tolerance, quantity, surface/condition, inspection and certificate requirements, packing preference and delivery destination. |
Final compliance is defined by the purchase order, approved drawing and issued mill documentation. Availability is confirmed for each grade, size and production route.
