1/4 Super Duplex 2507 SS Stainless Steel Coiled Tubing
1 / 4 Super Duplex 2507 SS Stainless Steel Coiled Tubing ASTM A789
Super duplex stainless steel 2507 (S32750) is a kind of stainless steel that PREN>40, containing 25%Cr and high molybdenum (>3.5%), high nitrogen (0.22% ~ 0.30%). 2507 duplex stainless steel has strong strength and corrosion resistance. It is mainly used in chemical processing, petrochemical industry and subsea equipment.It has strong resistance to chloride corrosion, high thermal conductivity and low coefficient of thermal expansion.The higher the content of chromium, molybdenum and nitrogen, the higher the resistance to spot corrosion, crack corrosion and general corrosion.
The chemical composition is shown in the following table:
| Grade | C≤ | Mn≤ | Si≤ | S≤ | P≤ | Cr | Ni | Mo | Cu≤ | N |
| S32750 | 0.03 | 1.2 | 0.8 | 0.02 | 0.035 | 24/26 | 6.0/8.0 | 3.0/5.0 | 0.5 | 0.24/0.32 |
