2507 Duplex Stainless Steel (UNS S32750) is a super duplex stainless steel with extremely high strength and excellent corrosion resistance, especially in high chloride ion environments. It is an upgraded version of 2205. It is often used in extreme corrosive environments such as deep-sea engineering, chemical processing equipment, and oil and gas platforms.
Chemical Composition
| Type | C | Si | Mn | P | S | Cr | Ni | Mo | Cu | N |
| 2507 | ≤0.03 | ≤0.8 | ≤1.2 | ≤0.035 | ≤0.02 | 24~26 | 6.0~8.0 | 3.0~5.0 | ≤0.5 | 0.24~0.32 |
Mechanical properties
| Type | T.S. | Y.S. | EL | HARDNESS( max) | BEND | |||
| Rm/Mpa | RP0.2/Mpa | A/% | HBW | HRC | HV | |||
| 2507 | ≥795 | ≥550 | 15 | 310 | 32 | ---- | ---- | |
Application
It is a two-phase stainless steel with good local corrosion resistance, especially the best resistance point, and has the characteristics of high strength, resistance to chloride stress corrosion and weldability. It is very suitable for heat exchange equipment with river water, groundwater and seawater as cooling medium in chemical, petroleum and petrochemical and power industry.
