Product Overview

2507 Super Duplex Stainless Steel Square Bar (1.4410 / X2CrNiMoN25-7-4 / SUS329J4L / 022Cr25Ni7Mo4N) is premium super duplex solid square bar, dual phase ferrite-austenite structure, manufactured per ASTM A276 and EN10088 standards. Hot rolled size:5×5mm~150×150mm; cold drawn minimum 3×3mm for heavy-duty critical components.

Higher chromium, molybdenum and nitrogen content than 2205 gives 2507 outstanding anti-corrosion performance in extreme chloride medium, seawater, brine and sour chemical environment. It is widely used for desalination equipment brackets, offshore oil & gas mechanical fixtures, flue gas desulfurization equipment, heavy-duty anti-corrosion molds. All products have full material test certificate.
