|---|---|
| Carbon (C) | 0.15% - 0.22% |
| Silicon (Si) | 0.20% - 0.50% |
| Manganese (Mn) | 0.30% - 0.60% |
| Sulfur (S) | ≤0.035% |
| Phosphorus (P) | ≤0.035% |
| Chromium (Cr) | ≤0.25% |
| Nickel (Ni) | ≤0.30% |
| Copper (Cu) | ≤0.30% |
Mechanical Properties
GOST 4543 seamless steel tubes are subjected to rigorous testing to ensure their mechanical strength, durability, and suitability for boiler applications. The following mechanical properties are typically observed:
| Property | Minimum Value |
|---|---|
| Yield Strength | ≥235 MPa |
| Tensile Strength | 380 - 520 MPa |
| Elongation | ≥25% |
| Hardness (HB) | ≤170 HB |
Steel Grade
The steel grade associated with GOST 4543 seamless steel tubes is determined by its mechanical properties, chemical composition, and intended use. Commonly used steel grades include 10, 20, 35, 45, and others.
Application
GOST 4543 seamless steel tubes find extensive application in the field of boilers. These tubes are crucial components in boilers that are subjected to high temperatures and pressures. They are used to construct various parts of boilers, such as water walls, superheaters, and reheaters. The seamless design ensures reliable performance and minimizes the risk of leaks or failures in the demanding boiler environment.
