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.
