Duplex stainless material families are commonly chosen where chloride resistance, stronger mechanical properties, and pressure-system reliability must be balanced together.
This page keeps the material view practical for client discussion: major grade families, typical product forms, use focus, and documentation expectations without unnecessary brochure clutter.
| Parameter | Typical Coverage | Notes |
|---|---|---|
| Common forms | Pipe, tube, fitting, flange, plate, bar | Form depends on pressure and fabrication requirement |
| Main grade groups | Duplex 2205 and super duplex 2507 type families | Selected against chloride severity |
| Service focus | Marine, offshore, seawater, sour and aggressive process duty | Strength and corrosion performance are both considered |
| Documentation | PMI, MTC, chemistry and dimensional review | Aligned to critical-service expectations |
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.
