What is 286 (ASTM A453 Grade 660) Fasteners ?

The base element in these 286 (ASTM A453 Grade 660) Fasteners is iron. It also contains nickel which is why it is also termed as a superalloy. Since it has a high content of nickel present in its chemical concentration it is said to be a nickel alloy more than a stainless steel.

286 (ASTM A453 Grade 660) Fasteners have excellent resistance towards corrosion and they can withstand corrosion and its damages up to 1300 degree fahrenheit. However, they have moderate resistance towards aqueous mediums. By the process of age hardening it is possible to increase and improve their strength. Even at highly elevated temperatures these 286 (ASTM A453 Grade 660) Fasteners are able to show great strength.
