4130 steel, often referred to as chromium-molybdenum steel, is known for its good weldability and machinability. Typically, it contains around 0.28% to 0.33% carbon, 0.8% to 1.1% chromium, and 0.15% to 0.25% molybdenum. This unique composition allows for significant strength without sacrificing ductility. It is commonly used in the automotive, aerospace, and structural industries.
As of October 2023, the price of 4130 steel is approximately $2.50 to $4.00 per kilogram, depending on several factors such as market demand, supplier pricing, and the type of finish. Prices can fluctuate based on economic conditions and raw material costs, so it's advisable to check with multiple suppliers for the most accurate and current pricing.
Several factors can impact the price of 4130 steel:
To better understand the value of 4130 steel, let's compare it with some alternative alloys commonly used in industrial applications.

Mild steel, which has a lower carbon content, typically costs between $0.80 and $1.50 per kilogram. It lacks the strength of 4130 steel, making it unsuitable for high-stress applications. Although cost-effective, it may not be the best choice for every project requiring significant strength and durability.
1020 steel is another alloy option, priced around $1.20 to $2.00 per kilogram. While it offers decent strength, it doesn’t have the enhanced properties found in 4130 steel, making it less ideal for applications that require both strength and ductility.
Stainless steel, known for its corrosion resistance, comes at a higher price, usually between $5.00 and $7.00 per kilogram. While 4130 steel provides superior strength, stainless steel is often favored for its aesthetic appeal and resistance to rust. The choice between these materials should be guided by environmental considerations as well as mechanical requirements.
In conclusion, 4130 steel is a compelling option for those in need of a strong, versatile material, particularly when strength-to-weight ratios matter. While its price of $2.50 to $4.00 per kilogram may be higher than some alternatives like mild steel, the added benefits often justify the cost. When selecting the right alloy, weigh your project's specific needs against the mechanical properties of the materials at hand.
Ultimately, whether you’re embarking on an automotive project or a structural application, understanding the costs and benefits of various steel alloys will equip you with the knowledge to make the best decision for your needs. Be sure to consult with suppliers and consider both the short-term and long-term advantages of each type of steel to ensure a successful outcome.
