Abstract
A metallic article of a Fe--Ni base, controlled linear thermal expansion alloy is provided with improved environmental resistance without detriment to mechanical properties through the application to and diffusion into the article surface of Cr with or without other coating metals such as Ni. The coating is preferably applied through the pack diffusion method.
