Jul 29, 2019 #6 EdStainless Materials May 20, 2004 15,893 0 36 US The outer surface will, but the properties through it will be lower, and maybe rather bad. If this pin is going to be loaded you might want to re-think your grade. = = = = = = = = = = = = = = = = = = = = P.E. Metallurgy, Plymouth Tube Upvote 0 Downvote

Aug 19, 2019 #11 Guest 1144 should respond very much like 1045, a very common material for which there is an abundance of data. "Everyone is entitled to their own opinions, but they are not entitled to their own facts." Upvote 0 Downvote
