TJC Steel Group is proud to introduce our EN10305-4 E235N precision seamless steel tubes, which are manufactured with utmost precision and quality, meeting the rigorous European standards. These tubes exhibit exceptional properties that make them suitable for a wide range of demanding applications.

Chemical Composition

The E235N grade steel used in these tubes boasts a carefully balanced chemical composition. The carbon content is limited to 0.22% maximum, ensuring good weldability and ductility. The manganese content is kept below 1.6%, while the phosphorus and sulfur content are both limited to 0.025% maximum. This composition results in a steel with high strength and durability.

Mechanical Properties

EN10305-4 E235N precision seamless steel tubes exhibit excellent mechanical properties. The tubes have a high tensile strength, ensuring they can withstand significant loads. The yield point of the material is also specified, indicating the stress level at which the material begins to deform plastically. The elongation rate is another crucial indicator of ductility, and these tubes offer good elongation properties.

Heat Treatment State

The tubes undergo a non-oxidizing bright heat treatment (NBK state) during the manufacturing process. This ensures that the tubes are free from oxide layers, improving their cleanliness and extending their service life. The NBK treatment also contributes to the tubes' excellent surface finish and dimensional accuracy.

Size Range

EN10305-4 E235N precision seamless steel tubes are available in a wide range of sizes. The outer diameter ranges from 4mm to larger dimensions, meeting the requirements of various applications. The tubes also comply with strict dimensional tolerances, ensuring their precision and reliability.

Impact Testing

To further ensure the quality and durability of our tubes, impact testing is performed. This testing involves subjecting the tubes to sudden impacts to assess their ability to withstand impact loads. The results of these tests provide valuable insights into the tubes' toughness and resistance to damage.

Primary Application Scenarios

The EN10305-4 E235N precision seamless steel tubes find extensive applications in various industries. Their high strength, precision, and durability make them suitable for use in hydraulic systems, automotive manufacturing, machinery construction, petrochemicals, and other demanding applications. The tubes' ability to withstand high pressures and complex deformations ensures their reliability in critical applications.
