I am searching for someone who has around 60' of 5150 steel in 2.5" diameter round stock. I can not use 4150 or 6150 due to the fact that this is for an aerospace gear and the customer will do destructive testing to insure that the correct material was used. I can not ask to use a substitute because to get that approved could take months. If anyone knows where this small quantity of material can be obtained without buying a mill run I would greatly appreciate the help.
