45# Seamless steel pipe introduction
45# Seamless steel pipe is a high-quality carbon structural steel, its carbon content is about 0.45%, so it is named "45#". It has high strength, good plasticity and toughness, and is widely used in machinery manufacturing, automotive, aerospace and other fields. Seamless steel pipe has higher strength and pressure resistance due to its non-weld characteristics, and is suitable for high-stress environments.

Main parameter
Chemical composition (typical value) :

  • Carbon (C) : 0.42-0.50%
  • Silicon (Si) : 0.17-0.37%
  • Manganese (Mn) : 0.50-0.80%
  • Phosphorus (P) : ≤ 0.035%
  • Sulfur (S) : ≤ 0.035%
  • Chromium (Cr) : ≤ 0.25%
  • Nickel (Ni) : ≤ 0.25%
  • Copper (Cu) : ≤ 0.25%

Mechanical properties:

  • Tensile strength: ≥ 600 MPa
  • Yield strength: ≥ 355 MPa
  • Elongation: ≥ 16%
  • Hardness: ≤ 217 HB (annealed)

Physical properties:

  • Density: 7.85 g/cm³
  • Melting point: about 1420-1460°C
  • Thermal conductivity: 46.6W /m·K (20°C)
  • Thermal expansion coefficient: 11.7μm /m·°C (20-100°C)

Standard
45# seamless steel pipe production and inspection in accordance with the following standards:

 

  • GB/T 8162: Seamless steel pipe for construction.
  • GB/T 8163: Seamless steel pipe for conveying fluids.
  • GB/T 17395: seamless steel pipe size, shape, weight and allowable deviation.
  • ASTM A106: Seamless carbon steel pipe for high temperature use.
  • ASTM A53: Standard for Welded and Seamless galvanized steel pipes.
  • DIN 1629: German standard for seamless steel tubes for general construction.

Specification
The common specifications of 45# seamless steel pipe are as follows:

  • Outer diameter range:
  • Small diameter: 6 mm - 89 mm
  • Medium diameter: 89 mm - 219 mm
  • Large diameter: 219mm-630mm
  • Wall thickness range:
  • Thin wall: 1 mm - 6 mm
  • Thick wall: 6 mm - 40 mm
  • Length:Usually 6 meters or 12 meters, can also be customized according to customer needs.

Peculiarity

  • High strength:45# steel has high tensile strength and yield strength and is suitable for high-stress environments.
  • Good processing performance:Easy to cut, forge and weld, suitable for machining.
  • Wear resistance:After heat treatment, the hardness and wear resistance are significantly improved.
  • No weld:Seamless steel pipe has no weld, the overall performance is more uniform, and the pressure resistance is stronger.
  • Wide range of applications:Suitable for mechanical manufacturing, automotive, aerospace and other fields.

Application field
45# seamless steel pipe is widely used in the following fields:

  • Machinery Manufacturing:Used to manufacture shaft, gear, connecting rod, piston and other mechanical parts.
  • Automotive industry:Used for manufacturing transmission shaft, half shaft, hydraulic cylinder and other components.
  • Aerospace:Used in the manufacture of aircraft landing gear, engine parts, etc.
  • Energy industry:Used in the manufacture of oil drill pipe, boiler pipe, high pressure pipe, etc.
  • Construction project:Used in the manufacture of steel structural support, bridge components, etc.
  • Hydraulic and pneumatic systems:Used to manufacture hydraulic cylinder, cylinder cylinder, etc.

45# seamless steel pipe is a high-quality carbon structural steel with high strength, good processability and wear resistance. It complies with GB/T 8162, GB/T 8163 and ASTM A106 standards and is widely used in mechanical manufacturing, automotive, aerospace, energy and construction engineering. Its weld-free feature makes it excellent in high-stress environments.
