Description

1.Introduction

HAYNES 282 alloy (UNS N07208) is a new, wrought, gamma-prime strengthened superalloy developed

for high temperature structural applications, especially those in aero and land-based gas turbine engines.

It possesses a unique combination of creep strength, thermal stability, weldability, and fabricability not

found in currently available commercial alloys. The new alloy has excellent creep strength in the

temperature range of 1200 to 1700°F (649 to 927°C), surpassing that of Waspaloy alloy, and approaching

that of R-41 alloy.

3.Easily fabricated

This high level of creep strength in HAYNES 282 alloy has been attained at a relatively low volume fraction

of the strengthening gamma-prime phase, resulting in outstanding resistance to strain-age cracking

(normally a problem with superalloys in this creep strength range). Additionally, slow gamma-prime

precipitation kinetics allow for the alloy to have excellent ductility in the as-annealed condition.

Consequently, HAYNES 282 alloy exhibits superior weldability and fabricability.



4.Heat treatment

HAYNES 282 alloy is provided in the solution-annealed condition, in which it is readily formable. The

typical solution-annealing temperature is in the range of 2050 to 2100°F (1121 to 1149°C). After

component fabrication, a two-step age hardening treatment is required to put the alloy into the

high-strength condition. The treatment includes 1850°F (1010°C) / 2 hours / AC (air cool) +

1450°F (788°C) / 8 hours / AC.



The features of HAYNES 282 alloy make it suitable for critical gas turbine applications, such as

sheet fabrications, seamless and flash butt-welded rings, and cases found in compressor,

combustor, and turbine sections. In augmented aircraft gas turbines, the new alloy will be useful

for exhaust and nozzle components. In land-based gas turbines, HAYNES 282 alloy is a good

candidate for transition sections and other hot-gas-path components.
