The term "St 37" for these tubes is based on a classification system that refers to the chemical and mechanical properties of the steel. "St" is the abbreviation for the German word "Stahl," which means "steel."
St 37 seamless steel drawing tubes offer excellent durability, high strength, and superior machinability, making them reliably used in various industrial applications such as construction, the automotive industry, and mechanical engineering. The number "37" indicates the approximate nominal tensile strength of the steel, which is around 370 N/mm² (MPa).
St37 steel drawing tubes are widely used in various industries for numerous applications. These tubes are manufactured according to a specific quality standard, typically defined by EN 10305-1.
St37 (E235) Steel Drawing Tube Properties
Seamless steel drawing tubes made from St37, produced using vacuum drawing processes, offer a more homogeneous structure, a more precise chemical composition, and superior mechanical properties. These features make them ideal solutions for precise industrial applications and projects that require high performance. Additionally, they can be subjected to various machining processes and manufactured with different properties for different applications.
Their weldability is good, and they can be easily welded with various welding methods. They also have good machinability. Due to their low carbon content, they are easy to form and weld. The corrosion resistance is low but can be improved through surface coatings or other protective treatments.
St37 (E235) steel drawing tubes can be used in a wide range of industrial sectors. They are commonly preferred in the construction industry, automotive industry, energy sector, mechanical engineering, and many other fields. Due to their high durability and flexibility, they provide reliable solutions for various applications.
These tubes are particularly used in hydraulic and pneumatic systems, precise piping work, and mechanical applications. The wide range of products offers suitable solutions for different projects and meets various requirements.
The chemical composition must contain specific amounts of elements such as carbon, manganese, phosphorus, and sulfur. These properties play a crucial role in the durability, formability, and machinability of the steel tubes.
