Hi
Just been asked to quote on some conveyor shafts in both Duplex 31803 & 316 stainless steel .
The shafts are mostly 25 Ø and 600mm long they are in a food factory but not in contact with product or caustic acids .
Typical conveyor situation lots of quick start stops etc but as for weight on conveyor that is just milk bottles .
As the shafts are supported on both ends in bearings ,they mostly fail at the moment in the middle because of breaking in 2 halves. So i wish to know if pricing in 304 & duplex would be better as there is no strenght benifit by using 316 . I believe at present they are made in 303 grade st/st.
many thanks in advance
