The term “hot extrusion” refers to any type of metal extrusion formed above the temperature at which rough metal recrystallizes during hot forging. The production of metal parts made of stainless steel, specialty steel, and other metals is appropriate for hot extrusion technology. The benefits of adopting the hot extrusion method include the ability to base complex sections, good metal-forming plasticity, good product quality, inexpensive tooling costs, and good processing of low plasticity and hard-to-deform materials.
