Surcharge Information

Due to the UK’s mostly commonly recognised surcharge mechanism no longer being openly published to the UK market we are unable to provide specific surcharge information on our website at this stage.

We are currently working with our suppliers to establish alternative mechanisms in order to provide a comprehensive and transparent view of global surcharge variations.

Look out for our improved surcharge pages appearing in the coming weeks.


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
  • Clutch plates

8620 steel is still often referred to as EN362 steel - its equivalent grade under the previous BS 970: 1955 standard.
