3/3/2014Dears! I works for a cement plant it is trial-run now The impeller of the ID fan (temp of airduct about 360 Deg C) and the raw mil fan were made from material mark: 13CrMo4-5 ( Cr: 0 7-1 15% Mo: 0 4-0 6% wt ) I think they will be worn-out very fast Can anyone have idea! Thank you very much Best regard
