HAYNES 25 with Excellent High-Temperature Strength and Good Oxidation Resistance
A-ONE ALLOY supplies HAYNES 25 in forms of plate, sheet, strip, round bar, forging, ring, plate, wire, capillary, tube, pipe. We are working with Advanced Technology & Materials Co., Ltd to ensure the technology is up to date and we are always ready to supply the best HAYNES 25 products to customers from worldwide.
HAYNES 25 is a Co-Ni- Cr-W alloy that combines excellent high-temperature strength with good resistance to oxidizing environments up to 1800°F (980°C) for prolonged exposures, and excellent resistance to sulfdation.
HAYNES 25 is ready to be fabricated and formed by conventional techniques, and has been used for cast
components. Other attractive features include excellent resistance to metal galling.

HAYNES 25 may be forged or otherwise hot-worked, providing that it is held at 2200°F (1205°C) for a time suffcient to bring the entire piece to temperature. The alloy has good ductility, and thus also may be formed
by cold working. The alloy does work-harden very rapidly, however, so frequent intermediate annealing treatments will be needed for complex component forming operations. All hot- or cold-worked parts should be annealed and rapidly cooled in order to restore the best balance of properties. The alloy can be welded by both manual and automatic welding methods, including gas tungsten arc (GTAW), gas metal arc (GMAW), shielded metal arc, electron beam and resistance welding. It exhibits good restraint welding characteristics.
Wrought HAYNES 25 alloy is furnished in the solution heat-treated condition, unless otherwise specifed. The alloy is normally solution heat-treated at 2150 to 2250°F (1175 to 1230°C) and rapidly cooled or water-quenched for optimal properties.
Annealing at temperatures less than the solution heat-treating temperature will produce some carbide precipitation in 25 alloy, which may affect the alloy’s properties.
HAYNES 25 alloy combines properties which make it suitable for a number of component applications in the aerospace industry, including parts in established military and commercial gas turbine engines. In modern engines, it has largely been replaced by newer materials such as HAYNES® 188 alloy, and, most recently, 230® alloy, which possess improved properties. Another area of signifcant usage for 25 alloy is as a bearing material, for both balls and races.
