Description

8620 grade steel is a low alloy case hardening steel.

After carburising / carbonitriding and hardening, it produces a hard wear resistant case with a tough core and good resistance to shock. The ‘as quenched’ surface hardness usually ranges from 37-43HRc.

This grade demonstrates reasonably high hardenability, and excellent forgeability and weldability.

For many applications it can be used as an alternative to more costly heavy alloyed case hardening steels.

Size Range

45mm - 280mm Dia

Typical applications of 8620 grade steel

  • Gears
  • Pins
  • Shafts
  • Camshafts
  • Drive wheels
