Haynes 188 is a cobalt-based alloy which possesses a unique combination of properties. It has excellent high temperature strength and oxidation resistance to 2100°F (1150°C) combined with good post-aging ductility.
Alloy 188 has average room temperature tensile properties in the bright annealed condition of 137.2 ksi (946 MPa) ultimate strength, 67.3 ksi (464 MPa) yield strength and 53% elongation. At 1800°F (980°C) the alloy has ultimate and yield strengths of 35.2 ksi (243 MPa) and 19.0 ksi (131 MPa), respectively, with 59% elongation. Cryogenic temperatures do not significantly affect the ductility of alloy 188, but strength levels are increased markedly.
The excellent oxidation resistance of Haynes 188 results from minute additions of lanthanum, which modifies the protective oxide scale in such a manner that the oxide becomes extremely tenacious and retards diffusion when exposed to temperatures through 2100°F (1150°C).
Haynes 188 exhibits good ductility after prolonged exposure at temperatures of 1200, 1400, and 1600°F (650, 760 and 870°C) for 16,000 hours.

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.
Performance Profile
Alloy L605 is the strongest of the formable cobalt alloys, useful for continuous service to 1800°F. Because of long and widespread use, this alloy has been the subject of many investigations to determine its properties over a wide range of conditions, thus making it an unusually well characterized material. Alloy L-605 is also known as alloy 25.
When exposed for prolonged periods at intermediate temperatures, alloy L-605 exhibits a loss of room temperature ductility in much the same fashion as other super alloys, such as X or 625.
Alloy L-605 is welded using gas tungsten arc, gas metal arc, shielded metal arc, electron beam and resistance welding. Submerged arc welding is not recommended. Use good joint fit-up, minimum restraint, low inter-pass temperature and cool rapidly from welding. For maximum ductility fabricated components should be annealed 2150-2250°F, rapid cool.
Corrosion Resistance
HAYNES 25 (L605) resistance to high temperature oxidation and carburization is good. The alloy, while not primarily intended for aqueous corrosion, is also resistant to corrosion by acids such as hydrochloric and nitric acid, as well as being resistant to wet chlorine solutions.

COMMENTS:
All customary machining operations are easily performed. M40 series high-speed tools are customarily used. M2 alloy and carbide tools have limited application and are not recom¬mended for end milling, drilling or tapping. Sulphur chlorinated, water-based cutting fluids work successfully when machining this alloy
