DIN2391 ST35 NBK seamless tube is a high-precision, high-finish steel tube, which is widely used in hydraulic systems, automobile manufacturing and other industries.
DIN2391 ST35 precision tube has no oxide layer on the inner and outer walls, and the inner wall is highly clean. It can withstand high pressure, cold bending without deformation, expansion, flattening without cracks, and can undergo various complex deformations and mechanical processing.
DIN2391 ST35 seamless cold-drawn tubes supplied by GNEE have specifications and delivery status of outer diameter usually 16-325mm, wall thickness usually 1-22mm, and delivery status NBK (bright oxygen-free normalizing). Packaging methods include bales or wooden box packaging, and surface treatment is to rinse the inner and outer surfaces of the tube with anti-rust oil.
