Super Duplex Bars
Super Duplex 2507 round bars for subsea equipment, offshore fasteners and seawater pump shafts.
Product Overview
Super Duplex 2507 pushes the duplex family further — higher chromium, molybdenum and nitrogen content deliver pitting resistance and yield strength beyond standard 2205, for the most demanding subsea and offshore machined components.
Bar stock covers pump shafts, coupling bolts and fasteners for subsea trees, risers and seawater-injection systems.
