Chemical Requirements of EN 10216

The chemical composition of our EN 10216 steel tubes is meticulously monitored to ensure the highest quality. For instance, our P235TR2 grade has a maximum carbon content of 0.16%, silicon at 0.35%, manganese at 1.20%, and other elements within specified limits. This careful balance of elements ensures the strength, durability, and reliability of our tubes, making them the preferred choice for various industries.

Steel Grades in EN 10216

At UNIACERO, we offer a range of steel grades under the EN 10216 standard, including P195TR1, P195TR2, P235TR1, P235TR2, P265TR1, and P265TR2. Each grade is tailored to specific applications and requirements, ensuring that our clients get the best fit for their projects. Whether you require tubes for room temperature applications or those with specified elevated temperature properties, we have a grade that meets your needs.

Production Tolerance of EN 10216

We understand the importance of precision in every project. That’s why our EN 10216 steel tubes come with strict production tolerances. For tubes with an outside diameter of less than 219.1mm, we maintain a tolerance of ±1% or ±0.5mm, whichever is greater. For larger diameters, the tolerances vary based on the tube’s dimensions, ensuring that every tube fits perfectly into your project without any discrepancies.
