Hi all,
Can anyone direct me to a source with a S-N curve for 12L14. I understand the additions of lead and sulfur to increase machineability tend to reduce fatigue properties. I can't seem to find any data that shows this.
Thanks in advance!
I found none. Indicating that there are no reliable fatigue properties for this grade. The closest that I can come is fatigue curves for steels with inclusions showing about a 40% drop in properties, even though the tensile, yield, and elongation are the same.
There is fatige S-N curves available from LaSalle's LA-LED grade. This material is for all practical purposes the same as 12L14 - i.e. low carbon, cold drawn, and full of inclusions. I will post summary via upload.
