For projects in Russia, Kazakhstan, and other GOST-standard markets, this product is commonly specified based on the following requirements:
Steel 45 is a medium-carbon steel grade offering a balance of strength, hardness, and machinability. Compared with lower-carbon grades such as Steel 20 and Steel 35, Steel 45 generally provides higher strength and hardness potential, while 09G2S is a low-alloy grade commonly used where low-temperature performance is required.
| Steel Grade | Carbon Content | Key Characteristics | Typical Applications |
| Steel 20 | 0.17–0.24% | Good weldability and ductility | General fabrication, structural components |
| Steel 35 | 0.32–0.40% | Moderate strength and machinability | Mechanical components, engineering applications |
| Steel 45 | 0.42–0.50% | Good strength, hardness, and machinability | Mechanical structures, equipment components |
| 09G2S | ≤0.12% | Low-alloy composition, good low-temperature performance | Structural and engineering applications |
For GOST 10704 Grade 45 Steel Pipe, the appropriate grade should be selected according to the required mechanical properties, weldability, operating conditions, and project specifications.
GOST 10704 Grade 45 Steel Pipe is primarily used in Russia, Kazakhstan, and other GOST-standard markets for mechanical and fabrication applications requiring good strength and machinability.
