Conical screw, double hole barrel

1. Material: 38CrMoAI A
Nitriding treatment, surface hardness: HV≥900
Nitride layer depth: 0.5-0.8mm
2. Material: The base material is 38CrMOAIA A. The surface of the screw edge is made of double alloy pour welding, which effectively improves the life of the screw.
3. Material: Base material 38CrMOAIA A. The wear-prone part of the material port is made of imported alloy steel. After special treatment, it can effectively improve the wear resistance of the barrel and extend its service life.

Product Details
