Abrasion-Resistant
In conveying applications where abrasion is a problem, Newton Conveyors’ hard-surfaced, abrasion-resistant screws afford an effective, practical and economical solution. Newton Conveyors’ hard-surfaced screws have been utilized successfully in numerous applications and can often increase normal service life over mild steel screws as mush as 500%. In certain applications, an ever greater degree of wear life may be obtained. To produce hard-surfaces screws, Newton Conveyors uses two different alloys which are applied to the carrying face of the flighting.
No. 1 Hard Face
No. 1 is generally used on medium weight helicoid screws and is intended for medium duty abrasive requirements. The material is a sweat-on paste composed of chromium boride crystals. Abrasion, corrosion and impact resistances are good and there is no noticeable build-up of the hard face area. No. 1 also produces excellent weldability characteristics and could be applied to the entire screw including the pipe.
No. 2 Hard Face
No. 2 is generally used on sectional screws and is intended for highly abrasive requirements. It is used only on the sides or edges of the screw flight and should not be used to coat the entire screw. Abrasion, corrosion and impact resistance are good and excellent weldability characteristics are obtained.
