Cold Bending Hollow Section

Cold bending hollow section is a cold rolled or cold drawn after processing high thick wall carbon steel pipe; Because of cold bending steel hollow inside and outside wall without oxidation layer, under high pressure without leakage, high precision, high finish, cold bending deformation, flaring, flattening without cracks, etc, it is mainly used to produce pneumatic or hydraulic components products, such as a cylinder or cylinder, are made with seamless tube. The chemical composition of cold bending hollow section with carbon sulfur C, Si, Si, Mn, Mn, S, P, P, chromium Cr.

The characteristics of cold bending hollow section

1. The thick wall degree is high, saves machining user quantity at the time of the loss.

2. Specifications, wide range of applications.

3. Cold rolled products of high precision, good surface quality, straightness is good.

4. The steel pipe diameter can make hexagonal.

5. Structural steel pipe is superior performance, more dense metal.

Seamless steel pipe and round steel, compared to solid steel in the bending torsional strength phase at the same time, the weight is lighter, is a kind of economic cross section steel, widely used in the manufacture of structural and mechanical parts. Cold bending hollow section in inherits the advantages of mild steel pipe at the same time, also has some characteristics of its own. Made the ring parts with thick wall and can improve the material utilization, simplifying the manufacturing process, material saving and processing time, such as rolling bearing ring, jack sets, etc., has been widely made from cold bending hollow section. Application of cold bending hollow section to save steel, improve the machining efficiency and reduce the processing process or equipment investment is important, can save cost and processing time, increase production and material utilization, at the same time to improve product quality, reduce costs, to improve the economic benefit is important. Generally higher requirements on the thick wall of the industry by cold bending hollow section, mostly with which do not require degree of thick wall seamless tube, after all, the same specifications hollow cold bending steel price is higher than that of seamless tube.

Without leaking, bear high pressure, high precision, high finish, cold bending deformation, flaring, flattening without cracks, etc, it is mainly used to produce pneumatic or hydraulic components products, such as a cylinder or cylinder, are made with seamless tube. The chemical composition of cold bending hollow section with carbon sulfur C, Si, Si, Mn, Mn, S, P, P, chromium Cr.
