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.
