Type 304 stainless steel also has outstanding welding characteristics. Post-weld annealing is not required to restore the excellent performance of this grade in a wide range of mildly corrosive conditions.Type 304L does not require post-weld annealing and finds extensive use in heavy gauge components where freedom from carbide weld precipitation is often required.
