Factors Influencing Screw Conveyor Design | Engineering Guide

Screw conveyors must be fabricated from abrasion resistant alloys. Typical materials of construction are AR235, AR400, AR500, TriBraze or chromium carbide overlay. These materials are harder and tougher than A36 carbon steel for resisting abrasion. The carrying face of the screw may be hardsurfaced with a weld-on hardsurfacing material.
