High-Strength Duplex Sheet

Duplex & Super Duplex Sheets

Duplex 2205 & Super Duplex 2507 sheets for offshore platform fabrication, chemical tanks and desalination equipment.

Duplex & Super Duplex Sheets
ASTM / ASME Certified Material

Product Overview

Duplex and super duplex sheet is fabricated into tank linings, offshore module cladding and marine equipment where standard stainless would risk chloride stress-corrosion cracking.

Both 2205 and 2507 are held in cold rolled, solution-annealed condition, ready for cutting and forming.
