What is 4130 Chromoly Tube
4130 Chromoly tube is a low-alloy steel made primarily of chromium and molybdenum. This combination gives it outstanding strength and durability while keeping the weight low, making it a top choice for many industries. Key properties include:
- High strength-to-weight ratio – strong yet lightweight for performance and efficiency
- Corrosion resistance – stands up well against rust and oxidation
- Excellent weldability – easy to join without compromising strength
- Toughness – resists wear, impact, and fatigue over time
Compared to regular carbon steel, 4130 chromoly tubing offers greater strength and corrosion resistance. It is also more cost-effective than stainless steel while still providing superior toughness and weldability.
This tubing meets industry standards such as ASTM A519 and MIL-T-6736B, ensuring consistent quality and performance for demanding applications.
Key Benefits of 4130 Chromoly Tubing
4130 chromoly tubing stands out for its superior strength and durability, making it a go-to choice when toughness matters. Its lightweight design is perfect for projects where cutting weight without losing performance is crucial, such as in motorsports or cycling.
You’ll also find it has excellent weldability and formability, which means it’s easier to shape and join without cracking or losing strength. Plus, it offers good corrosion and oxidation resistance, helping parts last longer even in harsh environments.
Thanks to these qualities, 4130 chromoly tube is highly versatile and widely used in industries like aerospace, motorsports, cycling, and structural engineering. Whether you need robust yet light tubing for a roll cage, a bike frame, or airplane components, chromoly steel tubing delivers consistent, reliable performance.
Applications of 4130 Chromoly Tubing
4130 chromoly tubing is a top choice across many industries because of its strength, light weight, and versatility. Here’s where you’ll often find it:
- Aerospace: Used in fuselages, landing gear, and various structural components where strength and weight savings matter.
