What is EN 10305-1 E235 Carbon Steel Pipes & Tubes?

EN 10305-1 E235 is one of the grades in this precision tube range, known for its exceptional dimensional tolerance and enhanced accuracy. The EN 10305-1 E235+C grade is delivered in the cold drawn condition to the buyer, available in schedules from SCH 10 to SCH 160 and XXS.

EN 10305-1 covers steel for producing precision piping grades. The EN 10305-1 Tube has a chemical composition that includes carbon, silicon, manganese, phosphorus, and sulfur, providing good strength and excellent tolerance to high temperatures and corrosive media in stress-induced environments. The EN 10305-1 Material has a tensile strength between 340 MPa to 550 MPa and can be elongated by 22%.

The EN 10305-1 Steel Tubes can be precisely shaped in various sizes and dimensions to meet different project requirements. This versatile grade is widely used in applications such as transmission shafts, fuel injection pipes, power steering systems, boiler equipment, and heat exchanger tubes.

The EN 10305-4 grade, marked by the letter E, ensures that precision tubes meet strict standards and tolerances ideal for machining parts, minimizing errors and mismatches within piping systems. One prominent grade in this range is EN 10305-1 E235, known for its exceptional dimensional tolerance and accuracy. The EN 10305-1 E235+C grade is delivered in a cold drawn condition, available in schedules from SCH 10 to SCH 160 and XXS. In contrast, the E235+N Pipe is supplied in a normalized condition, offering tight tolerance and superior mechanical properties and hardness. E235+C Carbon Steel Seamless Tubes, created by passing hot steel through extruded metal, exhibit remarkable load-bearing capacity. Indian-produced modules in this grade are more cost-effective due to the availability of abundant raw materials. For further details on pricing and product information, please contact us.
