Dear all Friends

Wonder if someone can give me a hand with my problem

I have to select the appropiated steel for building a screw conveyor
The mineral to be transported is a slurry and it will get into the screw conveyor at about 600 Celsius Degrees and it is quite abrasive.

The center pipe of the screw conveyor will have a flow of water for cooling purposes and also the Troughs will be build with an outer jacket for the same cooling purposes.

(The slurry goes out of the screw conveyor at 60 Degrees Celsius)

My problem is to select the steel ( 3/8") to manufacture the pipe, fligths and Troughs (in contact with the abrasive slurry) capable to withstand those high temperatures and at the same time to be abrasive resistance and of course, i am also trying to find a "workable" material

Any help will be very much welcome

Thank you in advance
