Message No. 5374, Started by kent on 11/30/00
I have a drawing for a small steel part used in an airplane propeller hub.  It is has very small splines and I guess it has to be broached.  The old drawing (circa 1944) calls out 1132 steel.  I can't find it in Machinery's Habdbook 25.  Usually 4130 is used in many aircraft applications.  But I am guessing the reason for 1132 is ease of machining.  It's not in a very critical application.  Can anyone tell me the exact equivelant or if there is a new number for the same steel?  And perhaps with today's state of the art machines, 4130 can easily be machined.  

Any suggestions?
