Description:

HAYNES 282 alloy (UNS N07208) is a, wrought, gamma-prime strengthened superalloy developed for high temperature structural applications, especially those in aero and industrial gas turbine engines. It possesses a unique combination of creep strength, thermal stability, weldability, and fabricability not found in currently available commercial alloys. The excellent creep strength in the temperature range of 1200 to 1700°F (649 to 927°C) surpasses that of Waspaloy alloy, and approaches R-41 alloy without sacrificing weldability.

Chemical Composition:

Ni	57.0 min	Cr	19.5
Co	10.0	Mo	8.5
Ti	2.1	Al	1.5
Fe	1.5 max	Mn	0.3 max
Ca	0.06	B	0.005

Applications:

sheet fabrications

Rings

Cases found in compressor

Combustion and turbine sections

Engines for aircraft

the transition sections and other hot-gas-path components in land-based gas turbines.
