We could produce A-286 Railway locomotive Traction Motors Non-magnetic Turbine Motor Generator Rotor Retaining Rings (UNS S66286, 1.4944, X5NiCrTi26-15, A286) from china
A-286 that is precipitation hardenable for high mechanical properties. The alloy maintains good strength and oxidation resistance at temperatures up to about 1300°F (700°C). The alloy's high strength and excellent fabrication characteristics make it useful for various components of aircraft and industrial gas turbines. Applications include blades, vanes, shafts, tail cones, afterburners, springs, and fasteners. This alloy is also used for automotive applications.

Hot Working/Forging
Alloy A-286 is rolled or forged from temperature of 1900/2050 °F(1038/1121 °C) using a short soaking period. It is slightly more resistance to deformation than the austentitic stainless steels during hot working. Do not forge below 1700 °F(927 °C).
Cold Working
In the solution treated condition,alloy A-286 can be satisfactorily cold drawn and formed. It is somewhat stiffer than stainless steels such as Types 316 and 310,and it work hardens rapidly.
Machinability
In general, the high temperature alloys are more difficult to machine than stainless steels. However, the iron-base alloy group, of which alloy A-286 is a member, is easier to machine than the nickel-based precipitation-hardening grades such as alloy 718 or cobalt-bearing grades such as alloy 41. Carbide insert tools are commonly used where possible.
