Solution Annealing
A heat treatment process where stainless steel is heated to 1000-1150C and rapidly quenched to dissolve precipitated carbides back into the austenite matrix, restoring corrosion resistance and ductility.
Solution Annealing Process
Solution annealing is the primary heat treatment for austenitic stainless steels. The material is heated above the carbide dissolution temperature, held for sufficient time, then rapidly cooled (water quenched) to prevent carbide re-precipitation.
