Abstract
PURPOSE: To control the residual stress of an austenitic stainless cast steel to a low level and to enhance the intergranular corrosion sensibility resistance thereof by reheating the steel to a specified temp. after slowly cooling it from the soln. heat treatment temp. or as cast.
CONSTITUTION: An austenitic stainless steel contg. C<0.12%, Si<2.0%, Mn< 1.5%, Cr 11W25% and Ni 8W13% is cast into a large-sized product, which is then reheated to 650W850°C as cast or after soln. heat treatment at 1050°C and slow cooling. In spite of large size the cast steel product has very little residual stress and undergoes no deformation. Metal carbide is prevented from precipitating at the grain boundaries, thus enhancing the intergranular stress corrosion sensibility resistance.
