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.


230M07 grade steel is a non-alloyed free cutting steel suitable for applications where good machinability is the prime consideration. It is typically used for the rapid production of parts which will not be subject to high stresses in service.

Case hardening can be carried out, but this steel is not recommended for general case hardening work and it is not intended for use where the hardened case is subject to severe impact in service.

This material should not be used for hollow parts which may be subject to internal pressure as the material does not possess good transverse properties.

Size Range

10mm - 80mm Dia

Typical applications of 230M07 grade steel

  • Light duty studs
  • Cycle components
  • Intricate non-critical components.

230M07 steel is still often referred to as EN1A steel - its equivalent grade under the previous BS 970: 1955 standard.
