A286 Springs
Alloy A286 Springs also known As Nicr A286 Springs are cold drawn and precipitation hardened manufactured from A286 Steel Wire. It has good Good corrosion resistance at elevated temperatures. A286 is a Nickel-Chromium alloy with the addition of aluminum to give outstanding resistance to oxidation and other forms of high temperature corrosion with the ability to maintain high mechanical properties at elevated temperatures. A286 Springs are used for applications that require high strength in temperatures from -320° to 950°F (-196° to 510°C)

A286 Compression Springs
A286 Extension Springs
A286 Torsion Springs
A286 Springs Typical Chemical Composition
Nicr A286 has a typical chemical composition makes them highly corrosion resistant with outstanding performance in extreme high and low temperatures. Alloy A286 Springs are nonmagnetic which is an important property for devices such as gyroscopes, chronoscopes, and indicating instruments with high electrical resistance.
