Product Description
3-60mm Hot Rolled Duplex 2507 Stainless Steel Plate for Pressure Vessel Fabrication
Our hot rolled duplex 2507 stainless steel plates (3-60mm) provide twice the compressive strength of austenitic steels, excellent anti-crevice corrosion, and thermal stability for pressure vessels.
Problem Statement
316L and 317L pressure vessels suffer from stress corrosion cracking (SCC) and weight penalties, especially in sour gas or high-chloride service.
Solution
Duplex 2507 offers higher strength, allowing thinner walls and lighter vessels. It resists SCC and pitting, and meets ASME SA-240 standards.

Applications
- Pressure vessels

- Offshore platform equipment
Technical Operation
The duplex microstructure (50% ferrite / 50% austenite) blocks crack propagation. High yield strength (≥550 MPa) reduces required material thickness.
Selection Guidelines
For temperatures up to 600°F and high chlorides, use 2507. For lower chlorides, 2205 is cost-effective. Verify impact test data for welded structures.
Frequently Asked Questions
Q1: Can 2507 be used for hydrogen service?
Limited; consult standards.
Q2: What welding method?
GTAW with over-alloyed filler.
Q3: Is heat treatment needed after welding?
Not usually, but avoid prolonged 750-1000°F exposure.
