EN10305-1 E235 Normalized Bright Cold Drawn Tube for Precision Systems
EN10305-1 E235 Normalized Bright Cold Drawn Tube (also referred to as EN10305-1 E235 NBK Seamless Tube) is a high-precision seamless steel tube conforming to the European Standard EN 10305-1. Its core material is engineering steel E235, guaranteeing a minimum yield strength of 235 MPa. The tube is formed through a cold drawing process to achieve precise geometrical dimensions and superior surface finish. It subsequently undergoes a normalized heat treatment to refine its grain structure, homogenize the microstructure, and stabilize its mechanical properties, resulting in a final bright surface condition. Renowned for its exceptional dimensional accuracy, consistent mechanical properties, and excellent surface quality, this product is widely used in demanding applications such as hydraulic cylinder barrels, precision mechanical components, and high-specification structural parts where tight tolerances and reliability are critical.
