| High Light | Bright Carbon Steel Seamless Tube ，Precision Steel Tube ASTM A29 ，Cold Rolled Carbon Steel Seamless Tube | ||
ASTM A29 4140 is a versatile alloy steel with excellent strength, toughness, and wear resistance. It is commonly used in various industrial applications where high strength and good machinability are required. The ASTM A29 standard covers hot-rolled or cold-finished carbon steel bars, including rounds, squares, and hexagons, in a variety of grades.
When it comes to tubing, the ASTM A29 4140 is available in seamless form. Cold rolled and bright carbon steel seamless tubing provides increased dimensional accuracy, smoother surface finish, and improved mechanical properties. This type of tubing is suitable for general applications where tight tolerances and good surface quality are essential.
The ASTM A29 4140 tubing exhibits several key features that make it a popular choice for various industrial applications:
High Strength: This steel grade offers excellent strength and hardness properties, making it suitable for demanding applications that require resistance to heavy loads and impact.
Good Machinability: The 4140 tubing can be easily machined due to its lower carbon content and the addition of chromium and molybdenum. It allows for the fabrication of complex parts while maintaining dimensional stability.
Wear Resistance: With a high carbon content, chromium, and molybdenum, this alloy steel offers superior wear resistance, making it ideal for applications that involve friction, abrasion, or wear.
Ductility and Toughness: Despite its high strength, ASTM A29 4140 tubing retains good ductility and toughness, providing reliable performance in harsh conditions.
The chemical composition of ASTM A29 4140 tubing is as follows:
| Element | Percentage Range |
|---|---|
| Carbon | 0.38 - 0.43% |
| Manganese | 0.75 - 1.00% |
| Phosphorus | 0.035% (max) |
| Sulfur | 0.040% (max) |
| Silicon | 0.15 - 0.35% |
| Chromium | 0.80 - 1.10% |
| Molybdenum | 0.15 - 0.25% |
The mechanical properties of ASTM A29 4140 tubing are:
| Property | Value |
|---|---|
| Tensile Strength | 655 MPa (95,000 psi) |
| Yield Strength | 415 MPa (60,000 psi) |
| Elongation at Break | 25% (in 50 mm) |
| Hardness | 217 Brinell (HB) |
The physical properties of ASTM A29 4140 tubing are:
| Property | Value |
|---|---|
| Density | 7.85 g/cm³ |
| Melting Point | 1416°C (2580°F) |
| Thermal Conductivity | 42.7 W/m·K |
| Electrical Conductivity | 6.57 % IACS |
The process performance characteristics of ASTM A29 4140 tubing are:
| Property | Value |
|---|---|
| Hot Working | 1100-850°C (2010-1560°F) |
| Cold Working | Good |
| Weldability | Preheating and post-weld heat treatment may be required |
| Machinability | High, but feed rates and tooling should be optimized |
The ASTM A29 4140 steel grade is commonly used in applications such as:
Alternative grades to ASTM A29 4140 include AISI 4130, 4340, and 6150, which have similar properties and can be used depending on specific requirements.
