ABSTRACT:
A method and apparatus for treating stainless steel material to reduce the carbon precipitation of the grain boundaries of the material as a result of temperature elevation due to welding, mechanical bending, or the like. The treatment includes the rapid heating of the material to the temperature at which the carbon will enter into solid solution followed by a rapid quenching of the heated material. Beneficial stress modifications are also achieved.
