This page exists to help the home shop machinists, casters, model makers across the globe to try and get some of the terminology straight - same or similar stuff, different name.

Please mail me if you think there is something that should be on this list ;-)

Note: The EN numbers date from the 1950's in the UK, there are new (and less memorable numbers) in use now like 817M040.  The EN numbers have been included as many model engineering plans date from this period.  Warning: the equivalents shown above are exactly that - as specifications vary slightly from country to country, they may not be identical in terms of composition or strength.
