The 4130 alloy steel streamline tube is a cold-drawn, seamless chromoly tubing designed for applications exposed to wind resistance. The streamlined profile offers up to 10 times less drag than round tubes. Manufactured to MIL-T-6736B standards, this tubing uses a major and minor axis to determine its size. Made from a unique blend of chromium and molybdenum, it is commonly known as Chromoly or Chrome Moly tubing. This strong and durable material is perfect for a wide range of applications. With its excellent strength-to-weight ratio, malleability, and corrosion resistance, it is suitable for race cars, motorcycles, aircraft, and heavy machinery in harsh environments.
