Description:
ledeburitic chromium cold work tool steel; with very small hardening deformations, very wear resistant, less resistant to impacts than NC11 / 1.2080, with good ductility, good cutting properties, much harder than NC10 and NC11/1.2080 due to content of molybdenum and vanadium
Application:
high performance cutting tools, broaches, milling cutters, reamers, blanking dies, dies, punches, rolling rolls, tools for cutting paper, marble and plastics, cold stamping and extruding tools
