  Applications
  SKD11 Tool Steel is used in the making of knife-edge mold, scissors, circular saw blades, metal stamping mold. Used to make cold work or hot work dressing dies, sides of rollers, screw lines, lines dies, transformer core stamping dies, rolled knives, steel tube forming rollers, special molding rollers, screw heading molds, etc. Also used for blanking dies, stamping dies and pressing dies with a thickness ≤ 6mm. It can also be found in the production of various kinds of scissors, inlaid blades and thread rolling dies. It is also used to make wear-resistant slider cold heading dies, deep drawing molding dies, cold extrusion dies and in the making of thermosetting resin molding dies and common plastic dies.
   
  Processing
