To control the distortion that occurs both during and after heat treatment, proper consideration must be given to such factors as design, composition, initial condition, machining procedure, and heat treatment. The design of a tool-steel part directly affects the susceptibility to shape distortion on heating and cooling. Limitations imposed by the design on composition, machining procedure, and heat treatment may indirectly affect both shape and size distortion. The figure shows the expected magnitude of shape distortion for this range of sizes. The difficulty involved in economically attaining the final dimensions of a part is largely determined by the magnitudes of the specified tolerance limits.
