Agricultural forged parts are critical force-bearing components of agricultural machinery power transmission and walking systems, which need to withstand huge torque, impact load and alternating stress during farm operation, so forging forming and heat treatment are essential processes.

Our factory uses hot die forging technology to produce agricultural forged spare parts with medium carbon alloy steel, followed by quenching and tempering heat treatment to greatly improve mechanical properties. Main products include forged drive shafts, gear blanks, half shafts, articulated connecting rods, pin shafts and spline shafts. These heavy-duty forged agricultural components are perfectly applied to the transmission systems of tractors, harvesters and cotton pickers of all mainstream brands, with strong wear resistance and anti-fracture performance. We can customize forged parts with different hardness standards according to working condition requirements and provide mechanical property test reports.
