SS12394 Super Duplex Steel Flange 2507

Super Duplex Steel Flange 2507 Description

Super Duplex Steel Flange 2507 is fabricated from duplex stainless steel (approx. 22–25% Cr, 5–6% Mo, and 0.2–0.3% N) that delivers enhanced resistance to pitting and crevice corrosion. The specified density and controlled melting range ensure consistent mechanical properties under high-pressure conditions. The flange design supports reliable joint integrity in demanding pipeline and pressure vessel systems, meeting rigorous industry standards.

Super Duplex Steel Flange 2507 Applications

1.       Industrial Piping and Pressure Systems
   - Used as a connecting flange in pipelines to achieve secure, leak-resistant joints by utilising its high mechanical strength and corrosion resistance.
   - Applied as a pressure vessel component to mitigate stress corrosion, ensuring structural integrity under cyclic loading.

2.       Chemical Processing Systems
   - Serves as a coupling component in chemical reactors to withstand corrosive media by capitalising on its balanced alloy composition.
   - Frequently used to facilitate maintenance safety in aggressive environments by providing reliable sealing and durability.

3.       Marine and Offshore Installations
   - Employed as a structural flange in marine piping systems to achieve long-term performance in saline conditions by utilising its dual-phase microstructure.
   - Applied in offshore platforms to support high-pressure connections, enhancing service life while resisting sea-water induced degradation.

Super Duplex Steel Flange 2507 Packing

Super Duplex Steel Flange 2507 is packaged in custom-moulded, shock-absorbent crates lined with anti-corrosive material. Each unit is securely wrapped to prevent surface abrasions and contamination. The packaging instructs storage in a low-humidity, temperature-controlled environment to preserve mechanical and chemical characteristics. Custom packaging options, including moisture barriers and labelling, are available on request.

Additional Information

Duplex stainless steels, including grade 2507, combine two metallurgical phases to deliver a balance of strength and resistance to corrosion. This hybrid microstructure offers advantages in environments where single-phase stainless steels may fail, particularly when exposed to chloride-rich or high-temperature settings. These materials are of increasing interest in sectors that demand both durability and longevity.

Understanding the metallurgical principles behind duplex alloys is essential when selecting components for critical systems. The relationship between chemical composition, thermal processing, and phase distribution plays a significant role in determining overall performance, which is crucial for long-term service reliability in industrial applications.
