GOST 5005 Grade 15 Grade 20 Cold Formed Steel Tube Electric Welded Steel Pipes for Cardan Shafts
Material
GOST 5005 specifies the requirements for cold-formed steel tubes, particularly those used in electric welded steel pipes for applications such as cardan shafts. The materials used in these pipes are designed to provide high strength, durability, and resistance to wear and tear.
Specification
The specifications for GOST 5005 Grade 15 and Grade 20 include dimensional tolerances, mechanical properties, and chemical composition. These grades are particularly suited for applications requiring high strength and toughness.
Key Features
- High Strength: Both Grade 15 and Grade 20 offer excellent tensile strength.
- Durability: Designed to withstand harsh conditions and mechanical stress.
- Weldability: Suitable for electric welding processes, ensuring strong joints.
- Corrosion Resistance: Treated to resist corrosion, extending the lifespan of the pipes.

Phosphorus (P) | ≤ 0.035 | ≤ 0.035 |
Sulfur (S) | ≤ 0.035 | ≤ 0.035 |
Silicon (Si) | ≤ 0.40 | ≤ 0.40 |
Chromium (Cr) | ≤ 0.25 | ≤ 0.25 |
Nickel (Ni) | ≤ 0.25 | ≤ 0.25 |
Mechanical Properties
Property | Grade 15 | Grade 20 |
Yield Strength (MPa) | ≥ 235 | ≥ 275 |
Tensile Strength (MPa) | 400 - 520 | 450 - 580 |
Elongation (%) | ≥ 20 | ≥ 18 |
Impact Toughness (J) | ≥ 27 | ≥ 27 |
Steel Grade
- Grade 15: Suitable for applications requiring moderate strength and toughness.
- Grade 20: Designed for higher strength applications, providing enhanced performance under stress.
Application
GOST 5005 Grade 15 and Grade 20 cold-formed steel tubes are primarily used in the manufacturing of cardan shafts, which are crucial components in automotive and machinery applications. Their high strength and durability make them ideal for transferring torque and motion in various mechanical systems.
Possible Alternative Grades
- S235JR: A European standard grade with similar properties, suitable for general structural applications.
- S355J2: Offers higher strength and is used in more demanding applications.
- ASTM A500 Grade B: An American standard for cold-formed steel pipes with comparable mechanical properties.
