Steel Specification Equivalents

Hi Peter

According to here 12L14 is the same as EN1A leaded.

Not found an equivalent yet for 1144 but this (a 669 page pdf!!) has jut about all the steels listed in it including 1144. I didn't see a direct equivalent but you can get the composition etc and then look for something suitable - or knowing what it's for, look to see if what we'd normally use in that application here is similar to the spec for 1144.

Happy hunting - you might be reading for some time!!

ps also look here and here (a Corusamericas pdf) only 8 pages this time - does 226M44 mean anything to you?

Hi again Peter

After a bit more digging it looks as though a number of reputable engineering companies are showing EN8M and EN8DM as pretty much an equivalent of the 226M44. This lists it as a free cutting steel, and other applications suggest it can be hardened. Unless you're making bits for real aircraft I would think you'd be OK with the EN8 or something a bit better.

My apologies to anyone trying to follow some of the links above, they've got a bit corrupted in pasting them into the posts.

The 669 page pdf on steel spec can be found at this url:-

The Corusamerica pdf is here:-

and finally in the second post  this is what "This" refers to:-

Why oh why do we still have to have different identities for the same chunk of metal in different countries - getting it all together and having one common (very extensive) series shouldn't be "rocket science" surely!

 Depends how its done. Proly it´s possible to carburize it, let cool slow, then heat to a hardening temp for the carburized skin; remeber the higher the carbon content the lower the heat is needed.  That means the inner core will not harden as much. This needs experimentation though. It´s common in the gun industry.
