Duplex Stainless Steel Round Bar: Duplex stainless steel is a mixed ferritic-austenitic family, not a single UNS alloy. Commonly specified grades include 2205 and super duplex 2507, but their chemistry and corrosion qualification differ.

Duplex Stainless Steel Round Bar — Technical Purchasing Guide
| Item | Reference / purchasing detail |
|---|---|
| Material/product | Duplex Stainless Steel Round Bar |
| Grade identity and purchase standard | Specify actual UNS grade such as S31803/S32205 or S32750 and purchase product standard |
| Delivery or treatment condition | Solution-annealed condition and tested corrosion/impact requirements as ordered |
| Typical applications | Corrosive-service shafts, valve components, process-industry and marine hardware |
| Selection concern | Avoid treating duplex 2205, 2507 and ordinary 316 as interchangeable corrosion-resistance materials. |
| Mozaic processing | Precision round-bar grinding, straightening, cutting, chamfering and packing when feasible |
Technical overview, not a certified composition or mechanical-property report. Confirm grade designation, product standard, required condition and heat-lot documentation for every order.
Why Material Grade and Condition Matter
Avoid treating duplex 2205, 2507 and ordinary 316 as interchangeable corrosion-resistance materials. Representative components include corrosive-service shafts, valve components, process-industry and marine hardware. Different grades can share a broad alloy family while requiring distinct finishing, inspection or material qualification. Procurement and engineering should agree on the supplied condition and part performance before accepting substitutions.
Precision Bar Supply and Processing
Mozaic Precision Metals offers project-specific centerless grinding, bar straightening, polishing, saw cutting, chamfering and packaging. Our quoting process considers material condition, diameter, length and the required final surface. Diameter tolerance, straightness and roughness should be specified and inspected separately.
