General Electric Material Specification 1

[cat253]

I have an old drawing which calls out two alternate materials both of which are I believe General Electric material specifications. they are B50E86B and B5F4M. Can anyone tell me what the equivalent materials would be in ASTM or AISI standards?

B5F4M should be similar to AISI 4140, 4142 or 4145.

I hate to be a wet blanket, but I think GE considers their material specs to be proprietary; they probably should not be published as part of answers to our forums...

The GE document does not state it is Controlled or Proprietary, without that it does not matter much what GE considers, unless the forum has a policy otherwise.
