4140 per SAE-AIR4127
4140 per SAE-AIR4127
(OP)
I have a current contract that requires 4140 per SAE-AIR4127. Does anyone no of a supplier? Every suppliers cannot offer with the AIR4127 spec. This requirement seems to be more of a material testing procedure and not a material spec.





RE: 4140 per SAE-AIR4127
Find an AMS (SAE) spec that covers the material form and quality of the 4140 stock you require. If you read thru the AMS spec carefully I'm sure you'll find that it conforms to SAE-AIR4127, which replaced FED-STD-66.
