Top 5 Properties of 4130 Tubing You Must Know: With Its 8 Applications

Main Text:

You are well aware that steel powers most cars, aeroplanes, and trains if we are not wrong. Do you know what makes steel a suitable choice for these transportation methods? The properties of 4130 steel, including its toughness and capability of getting machined and welded with ease. An impressive fact about this grade of steel is that it develops various mechanical properties that translate into a robust metal when it gets heated. Although, the chances are high that it may lose some machinability characteristics during this process. All in all, 4130 steel is an appropriate material for automotive, aeronautic, and aerospace engineering. So, if you want to buy 4130 tubing now, speak today to a customer-driven dealer of stainless steel in Missouri.

With that complete, it’s time to take a look at what 4130 tubing is:

What is 4130 Steel?

4130 Steel or Chromoly is a steel alloy made of chromium and molybdenum, containing 0.8 to 1.1% chromium and 0.15 to 0.25% molybdenum. Since 4130 steel is designated as low carbon steel, it offers high ductility, good weldability, and easy machinability.

What are the standard applications of 4130 Steel?

Knowing that 4130 steel has high strength and weldability, the manufacturers use it for different purposes, such as:

  1. Military aircraft
  2. Commercial jets
  3. Hydraulic functions
  4. Machine tools
  5. Automotive
  6. Aerospace
  7. Motorsports
  8. Welded tubing (in oil and gas industries)
  9. Car parts and machine components

What are the various properties of 4130 steel?

  1. Density – 7.85 g/cm3
  2. Machinability – 72% (in the annealed state)
  3. Hardness – 217 (Brinell scale) – 95 (Rockwell B scale)
  4. Ultimate Tensile Strength – 540 MPa
  5. Yield Tensile Strength – 460 MPa
  6. Modulus of Elasticity – 205 GPa

What are the primary characteristics of 4130 steel?

  1. Forging 

Do you know that 4130 steel is forged at a temperature ranging from 950 degree Celsius to 1230 degree Celsius? The steel alloy’s grain will become finer if the temperature is on the lower side during forging. While if the temperature is too low, it could affect the uniformity of the whole structure.

Thus, if that happens, it could be necessary to normalise it before heat treating the steel. If you don’t know what the term “forging” means, it is the capability of shaping metals by heating them in fire and hammering after that.

  1. Weldability 

The term “weldability” refers to the potential of metals to how easily they can get welded. And when it comes to 4130 steels, they are a breeze to weld owing to their low carbon content.

  1. Machinability

Machinability is any metal’s ability to get cut or shaped effortlessly while offering a smooth surface finish. And if we talk about 4130 steels, it is easy to get machined unless and until it has hardened.
