Product Description

Precision Seamless Steel Hydraulic Cylinder Pipe and Tube E235 NBK EN10305-1

EN 10305-1 is the European Standard application for specified steel tubes. The technical delivery conditions for seamless cold drawn steel tubes of the circular cross-section for precision applications with specified outside diameter D = 380 mm. EN10305 -1 Seamless Tube has high precision, excellent mechanical properties, is leak-free even under high pressure, has no deformation after cold-bending, and has no cracks when flaring and flattening, ensuring efficient operation in all services.
EN 10305-4 Grade Carbon Steel Seamless Tubes are also known as mild steel pipes and tubes. EN 10305-4 Tubes are low-cost Low Carbon Steel Tubes with a maximum carbon content of 0.17 percent and a manganese content of 1.20 percent that are easy to form and shape. EN 10305-4 Seamless Tubes are primarily used in the automobile industry, interior, and exterior architectural structures, water pipelines, gas lines, oil and gas industries, and so on.

Condition on delivery of EN 10305-1:

Term Symbol Explanation
(cold-finished as-drawn)
BK No heat treatment after the last cold-forming process. The tubes, therefore, have only low deformability.
(lightly cold-worked)
BKW After the last heat treatment, there is a light finishing pass (cold drawing) With proper subsequent processing, the tube can be cold-formed (e.g. bent, expanded) within certain limits.
Annealed GBK After the final cold-forming process the tubes are annealed in a controlled atmosphere or under vacuum.
Normalized NBK The tubes are annealed above the upper transformation point in a controlled atmosphere or under a vacuum.
