Alloy A-286 660 Class A Round Bars
Grade 660 is a precipitation hardening austenitic stainless steel widely used for high temperature fastening and bolting materials. Its relatively high nickel content for a stainless steel means that is sometimes categorized as a nickel alloy. The grade is commonly used for operating temperatures up to 700°C (1300°F).
Alloy A286 NAS 660 Inconel 660 UNS S66286 A-286 Alloy Heat Resistant Alloys, Super alloys or high performance alloys are of three types that include iron-based, cobalt-based and nickel-based alloys. These alloys can be strengthened by precipitation hardening, solid-solution hardening and work hardening methods. Super alloys contain good oxidation and creep resistance and are available in varied shapes. These alloys can function under high mechanical stress and high temperatures and also in places that require high surface stability. Super alloy A-286 is an iron-based high temperature and high strength alloy. The following datasheet provides an overview of super alloy A-286.
A286 is an iron-nickel-chromium alloy with additions of molybdenum and titanium. A 286 is one of the most popular high temperature alloys. As one of the austenitic alloys it maintains good strength and oxidation resistance at temperatures up to 1300ºF. Due to it's high strength and excellent fabrication characteristics A286 is used in various components of aircraft and industrial gas turbines. A286 is also widely used in the offshore oil and gas industry where the components are subject to high levels of heat and stress.
