EN10305-1 E355 +N Precision Seamless Steel Tube

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.
