SAF 2507 Duplex Stainless Steel
Standards：SAF 2507 ASTM A789 / A790 Grade（UNS）：S32750 Type：Duplex Stainless steel
SAF 2507 Duplex Stainless Steel Characteristics
SAF 2507 is a super duplex stainless steel with excellent corrosion resistance.
Duplex 2507 stainless steel has high compressive strength, impact strength and high thermal conductivity. These characteristics are suitable for many structural parts and mechanical components. It has a high impact strength and should not be exposed to temperatures higher than 570 ° f for a long time, which may weaken its toughness.
The duplex microstructure ensures high-stress resistance and mechanical strength of 2507 stainless steel.

Duplex 2507 stainless steel(UNS S23750) has high chromium and molybdenum content and strong corrosion resistance to organic acids
Duplex 2507 stainless steel(UNS S23750) also has strong corrosion resistance to inorganic acid
Compared with 904L stainless steel, duplex 2507 stainless steel(UNS S23750) duplex stainless steel has stronger corrosion resistance to sulfuric acid mixed with chloride ions. 904L is an austenitic alloy, which is specially used to resist the corrosion of pure sulfuric acid
- High compressive strength
- High impact strength
- High thermal conductivity
- High impact strength
Our duplex stainless steel grades
Duplex stainless steel is a kind of stainless steel composed of ferrite and austenite. The ferrite content is about 50%, and the austenite content is about 50%. This kind of steel has the characteristics of both austenitic stainless steel and ferritic stainless steel.
