Duplex stainless material families are commonly chosen where chloride resistance, stronger mechanical properties, and pressure-system reliability must be balanced together.
Duplex & Super Duplex Stainless Steel is reviewed around grade family, product form, service condition, testing scope, and documentation requirements before the suitable supply route is finalized.
| Parameter | Typical Coverage |
|---|---|
| Common forms | Pipe, tube, fitting, flange, plate, bar |
| Main grade groups | Duplex 2205 and super duplex 2507 type families |
| Service focus | Marine, offshore, seawater, sour and aggressive process duty |
| Documentation | PMI, MTC, chemistry and dimensional review |
Used where chloride exposure and stronger mechanical demands make standard stainless less suitable.
Final family is reviewed against corrosion profile, wall section, fabrication route, and project controls.
PMI, certification, and product traceability remain important throughout supply.
