Haynes 25 alloy is suitable for the forming of cobalt base alloy for the continuous 1800° F working environment. As a result of its long and extensive use, the alloy is used as an experimental object in a large number of working conditions.
Therefore, it is a material that has very good general characteristics. When exposed to long intermediate temperatures, Haynes 25 high temperature alloys show a small reduction in room temperature ductility, similar to other special alloys, such as alloys X and alloys 626.
Haynes 25 characteristics:
Excellent high temperature strength.
Oxidative resistance under 1800° F
Stand wear and tear
Resistance in seawater environment and acid fluid
Haynes 25 Application：
Gas turbine engine parts, such as combustion Chambers and enlarged combustion Chambers.
High temperature ball bearing and bearing ring.
Spring.
Heart valve.
Welding Technology:
Use tungsten electrode argon arc welding, gas shielded metal arc welding, manual arc welding and electron beam welding and resistance spot welding. Submerged arc welding is not recommended. Equipped with good joints, minimum braking current, low interlayer temperature welding, quick cooling after welding. In order to achieve maximum ductility, the parts manufactured should be annealed at 2150-2250° F and quickly cooled.
