Source UNS S32750 / S32760 Pipes & Tubes from verified mills, manufacturers and stockists on MetalMitra. Options span seamless, ERW and welded, produced to ASTM A790, and every order can ship with an EN 10204 3.1 certificate.
Choose seamless, ERW, welded or fabricated construction across a broad spread of diameters, wall thicknesses, schedules and lengths for process, pressure and structural lines.
UNS S32750 (2507) is a super duplex grade with very high strength and excellent resistance to chloride pitting and crevice corrosion. Super duplex stainless steel combines a balanced austenitic-ferritic microstructure with high chromium, molybdenum and nitrogen content, giving very high strength and excellent resistance to pitting, crevice corrosion and chloride stress corrosion cracking.
What you can source
- Seamless Pipes — The go-to choice for high-pressure and high-temperature lines.
- ERW Pipes — Economical welded pipe for utility and process piping.
- Welded / EFW Pipes — Fusion-welded construction for large-diameter runs.
- Tubes — Round, square and rectangular tubes, plus U-bends for heat exchangers.
Key properties
- High Strength — Roughly twice the yield strength of standard austenitic stainless steels.
- Chloride Resistance — Excellent resistance to pitting and crevice corrosion in seawater and brine.
- Stress Corrosion Resistance — Strong resistance to chloride stress corrosion cracking.
- Weight Saving — Higher strength allows lighter designs in suitable applications.
