ABSTRACT:
A process for warm-working a forged austenitic stainless steel workpiece to improve its mechanical and physical properties is disclosed. The workpiece is subjected to a force great enough to cause deformation while the surface temperature of the workpiece is elevated in the range of above about 200.degree. F. (95.degree. C.) to below the lower critical temperature. The purpose of using elevated temperatures is to reduce the force required to deform the workpiece. Stabilized austenitic stainless steel can be warm-worked and still maintain its corrosion-resistant properties. The advantages of warm-working over cold-working to achieve properties are reduction of noise and improved metallurgical control.
