The elementary function of an annealing solution is to reduce the hardness of the material and facilitate the progress of subsequent manufacturing operations. Annealing is commonly used after cold-rolling/cold-pilgering,cold drawing to soften materials and minimise residual stresses, improve machinability, and increase ductility by carefully controlling the microstructure. Many steels in pipes and tubes form are annealed, as are nickel alloy steels and stainless steels. Non-ferrous alloys are also annealed.

Solution annealing is applied commonly to austenitic stainless steels, typically at 1010-1150 Centigrade. With unstabilised grades, the treatment must be followed by rapidly cooling or quenching. It is applied as a softening process during manufacture or to optimise corrosion resistance.
