Luke Steel, based in Houston, Houstan, has built a solid reputation as a reliable manufacturer and supplier of top-notch EN 10305-1 / EN 10305-4 seamless tubing. They cater to a variety of industries, including automotive, hydraulics, precision engineering, and general mechanical applications. Renowned for their seamless precision tubes, Luke Steel guarantees exceptional dimensional accuracy and a smooth surface finish, ensuring that every tube adheres to stringent European standards. With cutting-edge manufacturing processes, thorough quality checks, and timely deliveries, Luke Steel is dedicated to providing customers with durable, high-performance seamless tubes that excel in applications where tight tolerances, leak-proof reliability, and longevity are essential for success.
The EN 10305-1 / EN 10305-4 seamless tubing is crafted from low carbon steel, containing approximately 0.10–0.20% carbon along with controlled levels of manganese and silicon to achieve the perfect balance of strength and formability. These tubes are known for their excellent dimensional precision, uniform wall thickness, and smooth inner and outer surfaces. Typically, they boast a tensile strength ranging from 500–700 MPa, along with good elongation properties, making them easy to bend, flare, and machine. Available in cold-drawn or normalized conditions, they provide consistent mechanical performance and leak-tight reliability for precision fluid and structural applications.
