Properties
HAYNES 25 (L605) is a non-magnetic cobalt based superalloy. HAYNES 25 (L605) maintains good strength upto 2150°F. AMS 5759 requires minimum yield strength of 45,000 psi at room temperature. HAYNES 25 (L605) maintains good oxidation resistance up to 1900° F. HAYNES 25 (L605) has a unique ability to resist corrosion in very severe environments. Highly resistant to hydrochloric acid, nitric acid and wet chlorine (subject to need for exercising care in its selection at certain con¬centrations and temperatures)
Hardenability
HAYNES 25 (L605) hardness is typically 250 BHN and never higher than 275 BHN by specification. Not significantly hardenable. Does not respond to customary aging treatments, but strain aging at relatively low temperatures (700-1100° F) can improve creep and rupture strength when the alloy is in service at temperatures under 1300° F. Also, tensile and creep strength can be improved by cold working. HAYNES 25 (L605) is an austenitic alloy.
