A-286

Description:

Super alloy A-286 (UNS S66286, W. Nr.1.4980, GH2132) is an iron-based high temperature and high strength alloy. A-286 is designed for applications requiring high strength and good corrosion resistance at temperatures up to 1300 °F(704 °C). This alloy offers high ductility in notched sections. In fact, the notched rupture strength of alloy A-286 is superior to many other commercial alloys with comparable high temperature properties. An advantage of this alloy is that it can be precipitation hardened and strengthened by heat treatments. This makes possible a high degree of uniformity in developing maximum strength, which can be duplicated application after application.

Super alloy A-286 is used in gas turbine forgings, fasteners, superchargers, cryogenic equipment, missile components, corrosive deep well hardware and jet engines.
