Haynes® 25 (L-605) is a cobalt based alloy that combines good forming and excellent high temperature properties. The alloy is resistant to oxidation and carburization to 1900 °F. Alloy 25 can only be hardened significantly by cold working. Cold working will increase creep strength up to 1800 °F and stress rupture strength uo to 1500 °F. Strain aging at 700 - 1100 °F improve creep and stress rupture strengths below 1300 °F.
