Why are truck repair tools made of carbon steel?

Carbon steel is often used as the material for large vehicle maintenance tools, mainly because it has many advantages in terms of performance, cost, and processability, and is particularly suitable for heavy-duty maintenance scenarios that bear large loads and large torques. The following are the specific reasons:

Carbon steel has good mechanical strength and rigidity, and can withstand the impact force and high-strength torque commonly seen in large vehicle maintenance, preventing deformation or breakage.

2. Strong wear resistance

During the maintenance process, tools often come into contact and rub against metal parts. Carbon steel, especially medium carbon steel and high carbon steel, have strong wear resistance after heat treatment (such as quenching and tempering), which prolongs the life of the tool.

3. Easy to process and shape

Carbon steel has good machinability and is easy to carry out:

Forging (such as wrenches and sockets)

Turning and milling (such as maintenance tools)

Heat treatment and surface treatment (such as chrome plating, blackening, etc.)

4. Excellent heat treatment performance

Carbon steel can obtain the required hardness and toughness after quenching and tempering, and adapt to different working conditions.

5. Low cost and easy to obtain

Compared with alloy steel, stainless steel and other materials, carbon steel is cheaper and more widely available, which is conducive to controlling manufacturing costs, and is particularly suitable for low-end or mass production.

6. Various surface treatments are available

Although carbon steel itself has average corrosion resistance, it can be treated with nickel plating, chrome plating, blackening, phosphating and other surface treatments to improve its appearance and rust resistance, taking into account both function and aesthetics.
