Detailed Product Description

Customized Surface Treatment Bearing Tube with Cold-rolled Seamless Steel Pipe

Product:BT1029 Seamless Steel Pipe

Bearing steel is special steel featuring high wear resistance and rolling fatigue strength. High-carbon chromium bearing steel, engineering steel and some types of stainless steel and heat resistant steel are used as materials of bearings and for other purposes.

Easony takes advantage of the high-cleanliness steel production technology in achieving the world’s top cleanliness and leads the bearing steel industry because of its high quality and reliability. We have also established a system to produce and offer steel bars, wire rods, tubes and formed and fabricated materials that match the process of each customer in terms of shape. Precision seamless steel pipe is a kind of high precision steel pipe after cold rolling or cold drawing. Full name: cold-rolled or cold-drawn precision seamless steel pipe. Due to the advantages of no oxide layer on the inner and outer walls of the precision seamless steel pipe, no leakage under high pressure, high precision, high finish, cold bending without deformation, flaring, flattening without cracks and so on
