In medium-sized machinery manufacturing, 4130 alloy steel forgings are mainly used to manufacture quenched and tempered parts with large cross-sections that work under high stress conditions, such as shafts, spindles, and high-load steering wheels, bolts, studs, gears, etc.;
In steam turbine and boiler manufacturing, 4130 alloy steel forgings are used to manufacture fasteners working below 450 °C, flanges and flange covers under high pressure below 500 °C.
4130 forgings advantages:
The advantages of SAE4130 forgings mainly include high strength and toughness, good machinability and weldability, corrosion resistance and wear resistance, good resistance to thermal expansion, and stability under high temperature conditions.
SAE4130 forging is a low alloy steel forging with the following significant advantages:
- High strength and toughness:
SAE4130 forgings can achieve higher strength through heat treatment and have good plasticity without reducing the toughness of the material, making it suitable for application scenarios with high loads and impacts.
- Good machinability and welding performance:
SAE4130 forgings have good machinability and welding performance, and can be easily connected and assembled, which is crucial for production efficiency in fields such as automobile manufacturing.
- Corrosion and wear resistance:
SAE4130 forgings have good corrosion resistance, especially after proper protection measures, which is crucial to the durability and life of automotive parts. In addition, it also has good wear resistance and can be used in machinery manufacturing, aerospace, automobile and other fields.
- Good resistance to thermal expansion:
At high temperatures, SAE4130 alloy steel has good thermal expansion resistance and is suitable for the manufacture of components under high temperature conditions. In the aerospace field, SAE4130 alloy steel is often used in applications requiring high strength and light weight, such as aircraft structural components and engine components.
