DETAILED INFORMATION

Gears, shafts, and fasteners are commonly made of low-carbon steel grade 45C8. This heat-treatable steel is often used in automotive and other machinery components. Steel EN8 is also known as EN8 steel. It can be heated. It is also highly machinable, has excellent dimensional stability, and has high wear resistance.

In addition to manufacturing mechanical components, steel grade 45C8 is used to construct structures and other applications requiring durability and strength. It is also easy to machine and form using conventional methods, in addition to its good weldability. The additional benefit of its low cost is that, compared to other types of steel, it is a much more economical choice for various projects.

In addition to its fatigue strength, it is also resistant to wear and impact, making it suitable for high-stress applications. 45C8 steel also has high compressive strength and good hardenability.

The steel grade 45C8 can be used for various applications, particularly in mechanical components, due to its versatility and cost-effectiveness.

Another important property of steel grade 45C8 is that it can be heat treated. It can be heat treated to increase its strength and hardness, making it more suitable for high-stress and high-load applications. The most common heat treatment processes for 45C8 steel are quenching and tempering. To rapidly cool steel, it is heated to a specific temperature and quenched in oil or water. The steel is then hardened at a lower temperature. In addition to increasing strength and toughness, it also improves flexibility.

Carbon is the key alloying element in 45C8 carbon plates of steel. Additionally, they contain up to 0.4% silicon and 1.2% manganese. These steels also contain residual elements such as copper, molybdenum, aluminum, chromium, and nickel.

In addition to axles, bolts, forged connecting rods, crankshafts, torsion bars, light gears, guide rods, screws, forgings, wheel tires, shafts, sickles, axes, knives, woodworking drills, hammers, etc., 45C8 steel grade round bar, steel plate, flat, and square are commonly used.

Factors such as manufacturing process, heat treatment, and microstructure can also affect the properties of 45C8 steel. Consequently, it is vital to consult the appropriate specifications and standards for the specific application and ensure that the steel meets the requirements.

It is also essential to consider machinability when using steel grade 45C8. It can be easily shaped and cut using conventional machine tools due to its good machinability. Therefore, it is ideal for applications requiring precise and intricate shapes. Turning, drilling, tapping, milling, and grinding can improve 45C8 steel’s machinability.

Due to its strength and machinability, It is also used to manufacture various types of fasteners, such as nuts, bolts, and screws. The material also manufactures gears, shafts, and other mechanical components. In addition to engine parts, gearboxes, and drive shafts, it is also used to construct various equipment and machinery.

A versatile and cost-effective steel grade 45C8 is well-suited for various applications due to its good mechanical properties and machinability. It is commonly used to manufacture mechanical components and fasteners and construct machinery and equipment. To ensure that the steel meets the requirements for the specific application, consult the appropriate specifications and standards.

Welding:

  • Before tempering components, allow them to cool to 180°C after welding.
  • Heat to 620 – 650°C at a maximum rate of 100°C/hour or 6000°C/thickness (mm)/hour, whichever is smaller. Temper for two hours. Cool to 200°C at a controlled rate of 100°C/hr. In still air, cool to room temperature. An intermediate, lower-temperature stress relief treatment may be necessary in highly restrained conditions

Alternative procedures (below) could be applied if it is not convenient to hold the component at an intermediate temperature after welding, pending heating for tempering. If restraint is very high, this alternative procedure may not prevent hydrogen-induced cracking.

 
Alternative procedure

  • The preheat should be increased to 250°C and held for at least four hours. 
  • Cool to room temperature at a maximum rate of 50°C per hour.
     
  • When convenient, temper.
