I would like to have informations on fatigue behavior of 25CD4.
Do you know maybe a web site with data such as wohler curves, or other informatin concerning 25CD4 ?
Thanks a lot.
Eventual preheating depends on the thickness and the nature of the steel (100°C). Interpasses temperature <200°C. A stress relieving heat treatment is advised in most cases, at 600°C during 2 hours
