Material and process characteristics

1. Substrate selection
   • High strength alloy steelLike 38CrMoALA, it has excellent mechanical properties and wear resistance.
   • Dual alloy structureThe surface of the spiral edges is made of imported alloy steel, combined with surface treatments such as nitriding and chrome plating, with a hardness of HRC58 ° -62 °, significantly improving wear resistance, corrosion resistance, and fatigue resistance.
2. heat treatment process
   • Optimize material structure and enhance mechanical properties through processes such as quenching and nitriding. The depth of the nitride layer is 0.5-0.8mm, and the hardness is 950-1020HV, ensuring long-term stable operation of the barrel.
