EN 10305-1 E355+sr seamless cold drawn steel tubes supplier
Solitaire Steel is a trusted exporter and supplier of high-quality precision tubes, including EN 10305-1 Grade E235 Tubes. This standard, EN 10305-1, covers seamless cold-drawn precision tubes made of steel. These tubes are produced with tight tolerances, ensuring high accuracy, which makes them ideal for machine parts and other precise applications.
The EN 10305-1 material is specifically designed to fit perfectly into the system it is used for, eliminating errors or mismatches. Industries prefer EN 10305-1 tubes because of their consistent quality, strength, and reliability. These tubes are typically manufactured with yield strengths of 235 N/mm² or 355 N/mm², depending on the application’s needs.
Additionally, these tubes are identified based on the treatment process they undergo. For example, a tube marked EN 10305-1 E235+N indicates that it has been normalized, improving its strength and performance. Similarly, tubes like E355+SR are stress-relieved for enhanced mechanical properties and durability.
Using EN 10305-1 precision tubes comes with multiple benefits. They offer superior mechanical strength and tighter tolerances, which are essential for high-precision systems. Furthermore, the cold-drawing process gives these tubes a smoother and more refined surface, improving their overall quality.
These features make EN 10305-1 E235 Tubes a reliable choice for industries requiring durable, high-performance steel tubes. Contact Solitaire Steel today to learn more or get a competitive quote for precision tubes!
EN 10305-1 Grade E235 Specification
EN 10305-1 Grade E235 Tubes are commonly known as mild steel pipes and tubes. These tubes are made from low-carbon steel, containing a maximum of 0.17% carbon and up to 1.20% manganese, which makes them easy to form, bend, and shape.
Manufactured according to the EN 10305-1 specification, these tubes are often referred to as CS pipes or MS pipes in the market. Since they are low-carbon steel tubes, they are not as hard as high-carbon steel pipes. However, their surface hardness can be increased through a process called carburizing, which adds strength to the outer layer of the tube.
These low-cost, versatile tubes are widely used across industries for applications requiring good formability, strength, and affordability.
