Product details
1.3243die steel
Detailed Introduction:
Characteristics and Scope of Application:
  For tungsten molybdenum series general cobalt containing high-speed steel, the red hardness and high temperature hardness have been increased, the wear resistance has been improved, and it has good cutting performance, but the strength and impact toughness are low, and it is easy to oxidize and decarburize. It is generally used as a gear cutting tool, milling tool, punch, tool head and other tools for cutting hard materials。
composition:
  carbon C :0.80~0.90(Allowable deviation:±0.01)
  silicon Si:0.20~0.45(Allowable deviation:±0.05)
  manganese Mn:0.15~0.40(Allowable deviation:+0.04)
  sulfur S :≤0.030
  phosphorus P :≤0.030
  chromium Cr:3.75~4.50(Allowable deviation:±0.05)
  nickel Ni:Allow residual content≤0.30
  copper Cu:Allow residual content≤0.25
  vanadium V :1.75~2.25(Allowable deviation:±0.05)
  molybdenum Mo:4.50~5.50(Allowable deviation:尺寸≤6,±0.05;尺寸>6,±0.10)
  tungsten W :5.50~6.50(Allowable deviation:尺寸≤10,±0.10;尺寸>10,±0.20)
  cobalt Co:4.50~5.50(Allowable deviation:±0.15)
  mechanical property:
  hardness :Delivery hardness:(Other processing methods)≤285HB; (annealing)≤269HB。Sample heat treatment system and quenching tempering hardness:≥64HRC
  Heat treatment specifications and metallographic structure:
  Heat treatment specifications:quenching,730~840℃ preheat,1190~1210℃(salt-bath furnace)或1200~1220℃(Box furnace)Heating, oil cooling,540~560℃ Tempering twice,every time 2h。
Delivery status: Hot rolled, forged, and cold drawn steel bars are delivered in annealed state, while hot-rolled and forged steel bars are delivered after annealing and other processing methods (such as peeling, light drawing, polishing, or polishing)
