Cr5Mo1V SKD12 Round Metal Rod
Cr5Mo1V is a high carbon, medium chromium, slightly deformed air-hardened cold work mould steel and alloy tool steel. The steel due to air quenching caused by the deformation of only manganese-containing oil quenching tool steel about 1/4, wear resistance between manganese-type and high-carbon, high-chromium tool steel, its toughness is better than any kind of good, especially suitable for the requirements of good wear resistance at the same time with special good toughness of the tool, widely used in the undercutting die and forming dies, rolls, punches, calendering moulds and rolling die, also used in some types of scissor blades.
