Product Description:
This 2507 super duplex stainless steel plate is manufactured to ASTM A240 standards at 8mm thickness for offshore subsea applications. With a Pitting Resistance Equivalent Number (PREN) of 40 or higher, it offers exceptional resistance to seawater corrosion, chloride attack, and erosion in high-velocity flow conditions. The super duplex microstructure provides approximately three times the yield strength of standard austenitic grades. Typical applications include subsea oil and gas pipelines, seawater lift pumps, offshore firewater systems, subsea manifolds, marine risers, ROV components, subsea control module housings, and splash zone equipment on offshore platforms.
