Cold rolled steel is low-carbon steel rolled and finished at room temperature, below its recrystallization point. This permits better control over finished product shape, dimensions, and appearance.Cold-rolled precision seamless pipe is a seamless steel pipe with high dimensional accuracy and good surface finish for precision mechanical structures, hydraulic equipment or steel bar sleeves.
Feature of cold rolled steel tube
Improved Surface Finish
The surface of cold rolled steel tubing is smooth and has fewer imperfections than hot rolled steel. This boosts aesthetic appeal and performance.
Advantages and disadvantages of cold rolled steel tube
Cold-rolled seamless pipe refers to a steel plate or steel strip processed into various types of steel by cold drawing, cold bending, cold drawing and other cold processing at room temperature.
Fast forming speed, high output, and damage the coating, can be made into a variety of cross-sectional forms to meet the needs of use conditions; cold rolling can cause large plastic deformation of steel, thereby improving the yield of steel point.
1.Although there is no thermal plastic compression during the forming process, there are still residual stresses in the section, which will inevitably affect the overall and local buckling characteristics of the steel;
2. The style of cold-rolled steel is generally an open section, which makes the free torsional stiffness of the section lower. It is prone to torsion when being bent, and it is prone to bending and torsion buckling when being compressed, and the torsion resistance is poor;
3. The wall thickness of cold-rolled steel is small, and there is no thickening at the corners where the plates join, and the ability to withstand local concentrated loads is weak.
Applications for cold rolled steel tube
With elevated surface characteristics and dimensional accuracy, cold rolled steel is suitable for technically precise applications or those where aesthetics are essential. Examples include:
Original Equipment Manufacturers, Or OEMs
Steel Service Centers
Store Fixtures, Displays, and Racks
Office And Institutional Furniture
Lawn And Garden
Recreational Vehicles, or RVs
