Material properties:
SAE4140 alloy structural steel is a high-strength steel, a 400 series martensitic stainless steel, mainly composed of chromium, molybdenum, manganese, silicon, and carbon. It has excellent strength and toughness and is suitable for manufacturing mechanical parts that require high strength, high rigidity, and high wear resistance. 1. Strength: The tensile strength of AISI 4140 is approximately 850 to 1000 MPa, and the yield strength is approximately 680 to 850 MPa. This makes it have very high tensile and yield strength; 2. Hardness: AISI 4140 can achieve high hardness through heat treatment. After quenching and tempering treatment, its hardness can reach 30 to 36 HRC (Rockwell hardness); 3. Machinability: AISI 4140 has good machinability and can be used for welding, heat treatment, and cutting. It also has high thermoplasticity and can change shape through thermoplastic deformation; 4. Heat resistance: AISI 4140 can maintain good strength and hardness at high temperatures. This makes it suitable for applications in high-temperature working environments, such as the oil and gas industry; 5. Impact strength: AISI 4140 has good impact strength and can resist impact and vibration loading. This makes it highly suitable for applications that require resistance to impact and vibration, such as mechanical engineering and transportation industries; 5. Corrosion resistance: AISI 4140 has moderate resistance to most general corrosive environments. However, in some strong acid or alkali environments, it may be corroded.
Metallographic structure:
AISI 4140 is a martensitic alloy steel material.
Application field:
1. Aerospace field: High pressure alloy seamless steel pipes are widely used in the aerospace field, mainly for manufacturing key parts such as hydraulic systems and fuel systems in aircraft, satellites, rockets, and other aircraft; 2. In the field of petrochemicals, high-pressure alloy seamless steel pipes are mainly used to manufacture equipment such as pipelines, valves, pumps, and containers. They are used to transport various corrosive media and ensure the normal operation of petrochemical production; 3. In the field of military products, high-pressure alloy seamless steel pipes are also widely used, such as in the manufacturing of hydraulic and transmission systems for military products such as ships, tanks, and armored vehicles; 4. In the field of electric power, high-voltage alloy seamless steel pipes are mainly used to manufacture high-temperature and high-pressure steam pipelines and key parts of various equipment, ensuring the normal production and transmission of electricity;
