Alloy 286/660 A/B/C/D

About Alloy 286/660 A/B/C/D

Alloy 286/660 A/B/C/D is a non-magnetic alloy which offers very high corrosion resistance, along with well retained high strength up to approximately 700˚C. Alloy 286 also shows good oxidation resistance up to approximately 800˚C. Alloy 286/660 can be age hardened to an elevated strength level.

West Special Fasteners are manufacturers of Incoloy Alloy 286/660 Fasteners.

Alloy 286/660 Fasteners such as Socket Capscrews, Nuts, Studs, Bolts, Washers, Studbolts, Socket Countersunk Screws, Socket Setscrews, Hot Forged items and machined components to drawings can all be produced at West Special Fasteners Limited.

We can also supply round bar in Alloy 286/660.

Alloy 286/660 A/B/C/D is used in a number of applications where high temperature and corrosion resistance is important. Alloy 286/660 has been used in applications such as high performance components in jet engines, turbines and after burner parts because of its first-class resistance in environments of elevated heat.

West Special Fasteners specialises in exotic metals and have supplied major UK companies with Alloy 286/660 A/B/C/D nuts, bolts etc.
