2507 is a kind of ferrite, austenite (two-phase) stainless steel, it has integrated many ferritic steel and austenitic steel is the most beneficial properties, because the steel chromium and molybdenum content is very high, so has excellent resistance to corrosion, crevice corrosion and uniform corrosion. Duplex microstructure ensures that the steel has a high resistance to stress corrosion cracking ability, and mechanical strength is high.

  

Standard in different countires:

ASTM/ASME:A240 - UNS S32750

EURONORM:1.4410 - X2 Cr Ni MoN 25.7.4

AFNOR:Z3 CN 25.06 Az

DIN/EN 1.4410ASME SA-240

 

Mechanical properties: SAF 2507 has high compressive strength, impact strength and low thermal expansion coefficient and high thermal conductivity. These features are suitable for many structural parts and mechanical parts. SAF 2507 high impact strength, should not be at a higher than 570 ° F temperature environment for a long time, which could reduce its toughness. Tensile strength: 730 mpa sigma b p;Elongation: delta 20% or higher
