2507 Stainless steel pipe/tube
2507 is a ferrite - austenitic (duplex) stainless steel with excellent resistance to pitting, crevice and uniform corrosion.
2507 is a ferritic-austenitic (dual-phase) stainless steel that combines the most beneficial properties of many ferritic and austenitic steels. Due to its high chromium and molybdenum content, the steel has excellent resistance to pitting, crevices and uniform corrosion.
Dual-phase microstructure ensures that the steel has high stress corrosion cracking resistance and high mechanical strength.
