【Abstract】 Austenitic stainless steel with good plasticity is considered to be used to produce screw for fixing the support of kinescope because it is suitable for cold heading and can bear large plastic deformation.To introduce the production technological process of ML0Cr18Ni9Cu3 austenitic stainless steel cold heading wire and the effects of every technological factors on the property of steel wire.It is indicated through study that when the grain grade of stainless steel wire is between 5.5～7,its ability of cold heading can satisfy the engineering demand.Meanwhile,it is thought that the requirement of stainless steel cold heading wire may be more and more largely along with the increasingly expanding of the use of stainless steel support,and the application prospects of the wire is good.更多还原
