*Since brazing is performed at temperatures within the hot-short range, strain must be
avoided during the brazing and cooling of this alloy.

The values listed above represent reasonable approximations suitable for general engineering use.
Due to commercial variations in composition and to manufacturing limitations, they should not
be used for specification purposes. See applicable A.S.T.M. specification references.
