Conical Twin Screw & Barrel

1. Meaterial:38CrMoAIANitriding treatment,Surface hardness:HV≥900Nitriding depth:0.5-0.8mm
2. Base material:38CrMoAlA A, a Special alloy is welded on the flight of the screw, prolonging the life of the screw.
3. Easy-wearing parts of the barrel made from anti-wear alloy can be abrasive performance.

Product Details
