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.

A hardness test will not tell what "kind" of material it is.
The only way to do this is with destructive testing. You have to isolate key elements in the steel to determine what grade it is. |
