General

CX13VD(W) is a carburizing stainless steel for structural applications, such as ball-screws.

Features & Benefits

  • Fully stainless
  • Simple martensitic solution
  • Classic heat treatment (no Cobalt)
  • Easy to carburize (low pressure or gas pressure with pre-oxidation)
  • High strength, ductility and tempering temperature (up to 300 °C)

Typical Applications

CX13VDW is used in the aerospace industry and industrial applications for:
  • Ball-screws (example: A380 horizontal stabilizer, 787 brakes)
  • Injection bodies for corrosive environment
  • Shafts with parts operating in corrosive environment (sea water).

Characteristics

  • Optimized composition and thermomechanical treatment to ensure carburizing process.
  • Gas quenching possible for reduced distortion.
  • After carburizing, quenching and tempering the surface hardness is around 730 HV.
  • Good toughness of the carburized layer.
  • High level of hardenability.
  • Good mechanical properties.
