AISI 316L Pickled Passivated Stainless Steel Marine Round Pipe

Our AISI 316L Pickled Passivated Stainless Steel Marine Round Pipe is specifically manufactured for the demanding conditions of marine, offshore, and coastal environments. The pickling and passivation treatment creates an optimized chromium oxide passive layer that delivers maximum resistance to chloride-induced pitting and crevice corrosion.

Key Features

  • 316L Marine Grade: With 2-3% molybdenum content, 316L provides exceptional resistance to chloride stress corrosion cracking – essential for saltwater exposure.
  • Pickled + Passivated Surface: Chemical pickling removes weld heat tint and surface contaminants, followed by passivation to rebuild a uniform, protective chromium oxide layer.
  • PREN ≥ 24: Pitting Resistance Equivalent Number exceeds 24, meeting requirements for seawater and marine atmosphere exposure.
  • DNV Certification Available: Det Norske Veritas marine classification society certification can be arranged for offshore projects.
  • Heavy Wall Options: Wall thickness up to 5mm for structural marine applications requiring high load-bearing capacity.

Applications

Specifically designed for offshore platform piping and structural components, marine vessel construction, coastal building facades and railings, harbor and dock infrastructure, desalination plant piping, and seawater intake/outfall systems.

Quality Assurance

Manufactured to ASTM A312 and EN 10217-7 standards. Intergranular corrosion testing (ASTM A262 Practice E), pitting corrosion testing (ASTM G48), and full PMI verification available with each shipment.
