4140 alloy structural steel is a grade in the American Standards Institute (AISI/SAE), and its equivalent material to the Chinese National Standard (GB) is 42CrMo. Here is a detailed analysis: 12
1, Chemical composition comparison

4140 (American standard)
Carbon (C): 0.38~0.43%
Manganese (Mn): 0.75~1.00%
Chromium (Cr): 0.80~1.10%
Molybdenum (Mo): 0.15~0.25%
The content control of other elements (such as phosphorus and sulfur) is relatively loose.

42CrMo (National Standard)
Carbon (C): 0.38~0.45%
Manganese (Mn): 0.50~0.80% (significantly lower than the American standard)
Chromium (Cr): 0.90~1.20%
Molybdenum (Mo): 0.15~0.25%
The control of phosphorus and sulfur content is stricter.

Difference point: The difference in manganese content may affect hardenability and thermal processing performance, so the two cannot be completely replaced in specific scenarios.
2, Mechanical properties and heat treatment
The tensile strength of 4140 is 795 MPa and the hardness is 241 HB. The tempered martensitic structure can be obtained through quenching (880 ºC oil quenching) and tempering (650-680 ºC), optimizing the overall performance.
The mechanical properties of 42CrMo are similar to those of 4140, but attention should be paid to the slight adjustment of the heat treatment process to adapt to the difference in manganese content
3, International equivalent grade
In addition to Chinese 42CrMo, 4140 also corresponds to the following international grades:
Germany: 42CrMo4
Japan: SCM440
Russia: 38XM.
4, Application Fields
Both are used for high-strength components, such as turbine fasteners, petroleum drilling tools, etc., but the more suitable materials need to be selected according to specific working conditions (such as corrosion resistance and hot processing requirements).

The commonly used materials for European standard seamless steel pipes include P195, P235, P265, P195GH, P235GH, P265GH, 13CrMo4-5, and 10CrMo9-10. These materials comply with EN10216-1 and EN10216-2 EU standards.
European standard seamless steel pipes also include materials such as S235JR and S355JR. S235JR is a commonly used structural steel material with good plasticity and welding performance, widely used in fields such as construction and mechanical manufacturing. S355JR is a low-alloy structural steel material with better strength and corrosion resistance than S235JR, suitable for applications under high pressure and load
In terms of specific applications, European standard seamless steel pipes are commonly used in boiler water pipes, smoke pipes, superheater pipes, and air preheating pipes, etc. They have high strength and corrosion resistance, and are suitable for various industrial fields
