EN32B

EN32B Grade Introduction:

EN32B is a carbon case hardening steel. Components when carburized have a core strength range of 430-490 N/mm2, with a hard-wearing surface. It is a popular case hardening steel grade for general engineering, readily machinable and weldable in its supply condition. EN32B is low tensile steel suited for lightly stressed components.

EN32B Grade Application:

  • collets
  • cams
  • rollers
  • bushes
  • spindles
  • gears

Forging Properties:

Heat slowly and uniformly to 1100°C. After forging cool slowly.

Stress Relieving:

After rough machining tools should be stress relieved. Soaking time 2 hours after the whole piece has attained a temperature of approximately 675°C. Cool in a furnace to approximately 500°C, and then freely in the air.
