Solution Treatment

・A heat treatment that uniformly dissolves alloying elements (e.g., chromium, nickel) into the austenitic or ferritic matrix of stainless steel.

・An essential process for maximizing the corrosion resistance and mechanical properties of stainless steel.

Main Purposes of Solution Annealing
１．Redissolution of precipitates (e.g., carbides)
２．Elimination of chromium depletion at grain boundaries
->Restoration of intergranular corrosion resistance
３．Homogenization and stabilization of the microstructure
４．Relief of stresses caused by cold working or welding
