When it comes to versatile steel alloys, 4130 steel stands out for its unique combination of strength, toughness, and weldability. Commonly used in a variety of industries, this steel is particularly favored in automotive and aerospace applications.

What is 4130 Steel?

4130 steel, also known as chromium-molybdenum steel, is a low-alloy steel that contains chromium and molybdenum as its principal alloying elements. Its composition typically includes:

• Carbon (C): approximately 0.28 - 0.33%
• Chromium (Cr): approximately 0.8 - 1.1%
• Molybdenum (Mo): approximately 0.15 - 0.25%
• Iron (Fe): remainder

This alloying provides enhancements in hardening and toughness, making it a preferred steel for numerous applications.

Applications of 4130 Steel

4130 steel is commonly used in various applications due to its durability and tensile strength. Some key applications include:

• Aerospace components: Used in aircraft frames and landing gear.
• Automotive parts: Common in roll cages, chassis, and suspension components.
• Heavy machinery: Ideal for parts that require high strength-to-weight ratios.
• Bicycle frames: Favored for its lightweight and sturdy characteristics.

Factors Influencing 4130 Steel Price per Kg

Understanding 4130 steel pricing is crucial for budgeting and project planning. The 4130 steel price per kg can fluctuate based on several factors:

• Market demand: Prices can rise during times of high demand.
• Raw material costs: Fluctuations in the cost of chromium and molybdenum can affect pricing.
• Production techniques: Advanced manufacturing methods may add to the overall cost.

Solutions for Common Confusions

1. What if I don’t know the specific grade needed?

   • Consult with your project engineer or a metallurgist to identify the right grade based on your project requirements.

2. How do I ensure quality when ordering?

   • Request mill test reports (MTRs) which provide assurance of compliance with the specifications.

3. Is 4130 steel machinable?

   • Yes, it can be machined with proper tooling and techniques; however, ensure to consider post-treatments for optimum results.

4. Can 4130 steel be welded?

   • Yes, it’s known for good weldability, but pre-heating is recommended to avoid cracking during the process.

Conclusion

In summary, 4130 steel is a robust, versatile alloy that finds applications across multiple industries, particularly where strength and durability are essential. Understanding factors that influence the 4130 steel price per Kg and considering particular buying factors can significantly enhance your project’s efficacy. Whether you’re in aerospace, automotive, or heavy machinery, choosing the right supplier with quality assurance can make all the difference.
