A286 Precipitation Stainless Steel Wire 660 UNS S66286 Round Bar
A286 Stainless Steel Wire 660 UNS S66286 Stainless Steel Round Bar
A precipitation hardening stainless steel, 660 (SUH 660, UNS S66286) maintains superior strength
at high temperatures up to 700℃, surpassing austenitic stainless steels.
With a higher nickel content than Type 304, stainless 660 also includes such elements as titanium
and aluminum for hardening.
Age hardening is used to precipitate γ' phase [Ni3 (Al, Ti)] making this an extraordinarily strong metal at high temperatures.
660 is a precipitation hardening alloy.
Its strength is increased through aging after solution heat treatment.
Two stages of heat treatment are generally carried out, as follows:
- Solution heat treatment: 980℃; oil or water cooling
- Age hardening: 720℃ × 16hr; air cooling
After solution heat treatment, either oil or water cooling is required, though air cooling is better for thinner metal.
Note that it is important to use a suitable temperature and holding time for aging to obtain the target strength.
