Creation of the favorable mechanical characteristics of the steels in the processes of cold extrusion

Experimental dates of the hardening of steel blanks and of the strains of cold forging were systematized whiz using the methods of mathematical statistics. Parameters of the technological process are discovered for making the cold forging blank, having high strong and high plasticity. 

 

Keywords: cold hollow blanks extrusion, blanks from strong steels, highhardening of steel blanks, parameters of the technological process, blank with high strong and high plasticity..
