We are precast concrete manufacturer, there is a issue concerning us which remain unsolved today is - our extrusion screw is very fast erode/ abrassive, which we need to repair or welding it everyday, this make our production inefficiency and costly.

Anyone got idea what materials if best for this kind of extrusion screw? our concrete products are formed by cement, coarse aggregate and also fine aggregate (sand).
