it makes a difference. I had chosen an Austenitic value to arrive at 1/7th turn equivalent, because my magnet didn't stick. I believe that RollCNY's Ferritic choice leads to a greater variance of equivalent to .3 turns when you account for 70° change.

but this page 9.8–25 5.4–14 Austenitic stainless steel shows CTE for one stainless steel up to even more than aluminum. Personally I have no idea which steel is in spokes.
