EN10305-1 E355 +N Seamless Steel Tube is a high-quality seamless steel tube designed for precision applications. It is manufactured to meet the stringent requirements of the European Standard EN 10305-1, which specifies the technical delivery conditions for seamless cold-drawn steel tubes with a circular cross-section. These tubes are characterized by their precisely defined tolerances on dimensions and specified maximum surface roughness, making them ideal for use in various industries where precision is crucial.
Key Features
High Precision: The tubes have tightly controlled dimensional tolerances.
Surface Finish: They offer a specified maximum surface roughness for better performance in applications.
Material Grade: E355 +N, which indicates a carbon steel with a minimum yield strength of 355 N/mm² and a +N modifier for nitrogen-treated steel.
Versatility: Suitable for use in automotive, mechanical engineering, hydraulic systems, and more.
Typical Applications
Automotive Industry: For components like transmission shafts and fuel injection pipes.
Hydraulic Systems: For high-pressure applications requiring precision and durability.
Structural Components: In mechanical engineering for parts that require high strength and precision.
