High carbon manganese steel main stockline auger

The invention discloses a high carbon manganese steel main stockline auger, which belongs to the field of transmission apparatuses for poultry. The high carbon manganese steel main stockline auger comprises the following main component elements: 0.8 to 1.2% of carbon, 11 to 13% of manganese, 1.5 to 2.5% of chromium, 0.4 to 0.8% of silicon, less than 0.7% of phosphorus and 1 to 3% of molybdenum. The high carbon manganese steel main stockline auger is a spiral special-shaped flat spring, has the characteristics of high tensile strength, elastic limit and fatigue strength, corrosion resistance, long service life and the like, and overcomes the problems of proneness to damage and corrosion and short service life of conventional main stockline augers made of materials like common stainless steel and carbon steel. The high carbon manganese steel main stockline auger provided by the invention can be used in a transmission apparatus for poultry and has a wide application scope.
