UNS S32750 (F53 / 1.4410 / Alloy 2507) exhibits a low coefficient of thermal expansion and higher heat conductivity than austenitic steels and is suitable for working temperatures up to 300°C. Listed in NACE MR 01 75 for sour service UNS S32750 (F53 / 1.4401) and having gained ASME Approval for Pressure Vessel applications Alloy 32750 can be
ASTM A240 UNS S32750 Super Duplex Stainless Steel Plates and Sheets Packing ASTM A240 UNS S32750 Super Duplex Stainless Steel Plates and Sheetsis sleeved into plastic bag individually, pieces wrapped with water-proof material, bundled with nylon rope.
S32750 and S32760 are both super duplex stainless steels (SDSS).As such, their microstructure is a combination of austenitic and ferritic grains, which imparts the most favourable properties of each. They are based upon a 25% chromium content (25Cr), but differences in their mechanical properties, physical properties and composition are small.
The pitting corrosion resistance of S32750 super duplex stainless steel, annealing treated at temperatures of 950–1200 °C for 20–60 min, was investigated using potentiodynamic polarization tests. The results show that the volume fractions of ferrite in the S32750 duplex stainless steel increased from 48.9% to 68.4% as annealing …
