1 / 4 * 0.049 Duplex 2205 Stainless Steel ControL Line Tubing ASTM A789
Tiptop offers a variety of duplex stainless steel, super duplex stainless steel welded and seamless tubing, depending upon the properties the tubing is required to exhibit. Other alloys and sizes are also available upon request. Duplex stainless steels (named for their austenite and ferrite compositions), has greater yield strength than austenitic stainless steel.
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 |
