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.


41Cr4 grade steel is a low alloy steel that possesses good tensile and shock resistance properties restricted to sections of approx. 4”.

Its resistance to wear can be considerably increased by flame hardening or nitriding (for maximum wear and abrasion resistance).

Bars can be supplied in quenched and tempered condition with tensile strength exceeding 800 N/mm2, but are also available in the softened, more machineable state suitable for further heat treatment.

Typical applications of 41Cr4 grade steel

  • Axle shafts
  • Crankshafts
  • Gears
  • Induction hardened pins
