I've got to repair some [reasonably minor] torch cuts on both my M2HB bottom and top plates, but want to first confirm that they are made from 4140 steel (this is a guess on my part). Alternately, [again I'm guessing] were the top & bottom plates made of Armasteel? Can anyone confirm either of these guesses, or alternately tell me the correct steel?

the print calls out 4140


Thanks Karl! Exactly the information I needed. And, I'm all set up for 4140 TIG welding (i.e. pre-heat, post-heat, anneal, etc.).

Related question - are the prints available anywhere? I've look around, including on the zipped CD in the sticky area, but no luck.
