2507 / 2507 / S32750 / 1.4410 Stainless Steel Seamless Tubing ASTM/ASME SA789/790M
2507 is a ferritic-austenitic (duplex) stainless steel that combines the most beneficial properties of many ferritic and austenitic steels. Due to the high chromium and molybdenum content of the steel, it has a very high Good resistance to pitting corrosion, crevice corrosion and uniform corrosion. The two-phase microstructure ensures that the steel has high resistance to stress corrosion cracking and high mechanical strength.
