TORICH Annealing and Tempering 42CrMo4 40CrNiMo Carbon Alloy Forging 1. Brief introduction: What is the forging: Forging is a processing process. A forging is an object in which a metal is subjected to pressure to shape the required shape or suitable compression force through plastic deformation. This force is typically achieved through the use of a hammer or pressure. The forging process creates a fine grain structure and improves the physical properties of the metal. In the
