Applications of 40Cr material

After 40Cr alloy steel quenching and tempering treatment, it is used to manufacture medium-speed, medium-load parts such as machine gears, shafts, worms, spline shafts, thimble sleeves, etc.

After quenching and tempering and high-frequency surface quenching, it is used to manufacture high-hardness, wear-resistant parts such as gears, shafts, spindles, crankshafts, sleeves, pins, connecting rods, screws, nuts, intake valves, etc.

After quenching and medium temperature tempering, it is used to manufacture heavy-duty, medium-speed impact parts such as oil pump rotors, sliders, gears, spindles, collars, etc.

After quenching and low temperature tempering, it is used to manufacture heavy-duty, low-impact, wear-resistant parts such as worms, spindles, shafts and collars.

After carbonitriding treatment, it is used to manufacture transmission parts with large size and high low temperature impact toughness, such as shafts and gears.
