THERMAL STABILITYHAYNES® 188 alloy is similar tothe solid-solution-strengthenedsuperalloys, such as alloy 625or HASTELLOY® X alloy, whichwill precipitate deleteriousphases upon such long termexposure. In this case, thephase in question is a C02Wlaves phase, which serves toimpair both tensile ductility andimpact strength. The behaviorof 188 alloy is significantly better in this regard than HAYNES25 alloy, which it replaced; butfor applications where thermalstability is important, 230° alloyis recommended.EXPOSURE TEMPERATURE (°C)AT 500 600 700 800 900 1000I I I I I I2 ~ .
