The elbow made by the cold extrusion process of internal and external die is beautiful in appearance, uniform in wall thickness and small in size deviation. Therefore, the cold extrusion manufacturing process is applicable to the production and manufacturing of thin-wall stainless steel elbow. The wall thickness deviation of tube billet is also demanding.
