40cr steel plate is the standard for alloy steel used in China's GB engineering machinery and is one of the most widely used steel grades. After quenching and tempering treatment, 40Cr steel has good comprehensive mechanical properties, good low temperature impact toughness, low notch sensitivity, good hardenability and high fatigue strength of cold oil. When 40Cr steel is water-cooled, the shape of the parts is complicated, cracks are easy to occur, and the cold-bending plasticity is medium. After normalizing, the 40Cr steel plate has good machinability, but the 40Cr steel plate has poor weldability, and should be preheated before welding, generally used for quenching and tempered state.
The application of 40Cr material is used for the manufacture of medium-speed and medium-load parts such as machine gears, shafts, worms, spline shafts, bushings, etc. after quenching and tempering of 40Cr alloy steel.
After quenching and tempering and high-frequency surface quenching, 40Cr alloy steel plate is used to manufacture high-hardness and wear-resistant parts such as gears, shafts, spindles, crankshafts, bushings, pins, connecting rods, screws, nuts and intake valves.
After quenching and medium temperature tempering, 40Cr alloy steel plate is used to manufacture heavy-duty and medium-speed impact parts such as oil pump rotors, sliders, gears, spindles and collars.
After quenching and low temperature tempering, 40Cr alloy steel sheets are used to make heavy-duty, low-impact, wear-resistant parts such as worms, spindles, shafts and collars.
After being carbonitrided, the 40Cr alloy steel plate is used to manufacture transmission parts such as transmission shafts and gears with large size, high and low temperature impact toughness.
