Method of thermal or thermomechanical treatment of precision steel components

摘要

Method of thermal or thermochemical treatment of precision steel components. The components having different wall thicknesses after hardening, subjected to a partial low temperature cooling so that the reduction of the primary residual austenite occurs preferably at the points treated. By this partial low temperature cooling, undesired influence on the mechanical properties of the precision components in their thin-walled regions is avoided.
