Heat Treating of Gray Irons: Part One :: Total Materia Article
The heat treatment most frequently applied to gray iron, with the possible exception of stress relieving, is annealing. The annealing of gray iron consists of heating the iron to a temperature high enough to soften it and/or to minimize or eliminate massive eutectic carbides, thereby improving its machinability.

Steels (High Chromium Steels) Stainless Steels
Apr 12, 2001· Martensitic Stainless Steels. High carbon high chrome steels are heat treatable as a consequence of the higher carbon content, and are known as martensitic stainless steels ( 410, 416). They do, however, exhibit lower corrosion resistance due to chromium depletion of the oxide film. They exhibit good strength and oxidation resistance up to 750°C, although their creep strength above 600°C .
