What is SAF2507? Stainless Steels
SAF2507 is a registered trademark of Sandvik Intellectual Property AB. SAF stands for Sandvik Austenite Ferrite, whilst 2507 references the UNS S32750 caption. Sandvik have optimised the composition and production of this super duplex stainless steel in order to maximise the mechanical properties and corrosion resistance.
SAF2507 is based upon a 25% chromium content, in keeping with other super duplex stainless steels such as Ferralium 255 and Zeron 100. With a pitting resistance equivalent number (PREN) >40, corrosion resistance is extremely good – super duplex stainless steels are recommended for applications requiring long-term immersion in seawater. Yield strength is typically 3-4x that of a regular Alloy 316L grade.
Langley Alloys stocks a complete range of SAF2507 from 20mm diameter to 450mm diameter solid bar.
