I found someone at Cal Poly willing to help me with annealing and rehardening 901 internals so I can machine them. He said it would be helpful to know what alloy the steel is. He also asked if they were case hardened.

Gears are typically made of 8620 steel, then carborized (sp).
Shafts can be made of lots of different things depending on the application. Could be 4140 heat treated or even something as exotic as Jethete. If you are trying to match steel components you could always send a scrap piece to a testing lab and for about $200.00 they can tell you what grade of steel it is. Good Luck (IMG:style_emoticons/default/boldblue.gif) |
