Solubilization is the heat treatment used for austenitic steels (stainless and duplex). It consists of a high temperature heating (1000-1100 °) in order to ensure the solubilization of the alloy elements within the austenitic grains; then follows a rapid cooling of the piece (in air or in water) to prevent the chromium carbides from precipitating.

What is solubilization used for? This treatment is used to improve the characteristics of the steels, therefore: mechanical strength, corrosion resistance and oxidation resistance.
