ETD 150

[11secondlx]

Has anyone found any S-N curves on this steel? It is widely used for shafting, and is a Modified 4100H alloy steel. I have not been able to find any info on this, small company makes it.
Any information would help!!!!
P.S.- It is ETD 150, if you didn't get that from the title.

aedmotorsports. they are the bomb. can get that stuff for around 25 bucks a foot throught them. But you might as well just use 300m. Better stuff and only a couple bucks more a foot than etd 150.

Cool, we get a lot of crap from them. I appreciate the advice. What is this 300m stuff you are talking about?
Thanks again,

it is modified 4340. Pretty much as good as it gets for axle/jackshaft material. Stupid strong. Hard on the tools though. If you have the right inserts it shouldnt be to bad for you.
