1. Automobile Manufacturing Field
In this field, AISI 4340 steel is most commonly used to manufacture quenched and tempered parts that require high strength and wear resistance for automobiles, including engine crankshafts, brake system components, gears, transmission shafts, connecting rods, bearings, axle heads of vehicle frames, springs and spring leaves of vehicle suspension systems, etc. Using ASTM 4340 alloy steel to manufacture these quenched and tempered parts, it can meet the requirements of high-speed rotation, large loads, impacts and vibrations during automobile driving with its excellent performance.

2. Industrial Machinery Field
The quenched and tempered parts made of 4340 alloy steel are mainly used in various mechanical equipment, meeting the requirements of high efficiency, stable operation, durability and wear resistance of mechanical equipment during manufacturing and operation. It is mainly used to manufacture high-load shafts of heavy machinery, hydraulic and mechanical transmission parts, transmission gears, bolts and nuts, bearings of large machinery, turbines and rotors of rotating machinery, drive shafts, pins, turbine shafts, connecting parts of heavy machinery, etc.

3. Oil And Gas Industry
Alloy 4340 material can be used to manufacture various quenched and tempered parts that withstand harsh conditions such as high pressure, high torque and high temperature to ensure the long-term stable operation of the equipment. In this field, ASTM 4340 alloy steel is usually used to manufacture transmission parts, pump shafts, axial compressor shafts, drill bits, valves, high-pressure vessels and other quenched and tempered parts of oil drilling equipment.

4. Aerospace Field
ASTM 4340 alloy steel has high hardness, strength, toughness and fatigue resistance, etc., which meets the needs of manufacturing key quenched and tempered parts related to aircraft, ensuring the safe operation and reliability of aircraft. It is mainly used to manufacture large-sized important quenched and tempered parts on aircraft, including helicopter rotor shafts, wheel shafts, gears of power equipment, engine shafts, rotor shafts, turbine blades, structural parts, crankshafts, propeller shafts, fasteners, etc.

In addition to the above fields, ASTM 4340 alloy steel is used to manufacture various quenched and tempered parts in the fields of shipbuilding, military industry, electric power, railways, tools and molds, etc.
