honed cylinder tube is a kind of high precision steel tube material after cold drawing or hot rolling. Because the inner and outer walls of the quilted cylinder tube have no oxide layer, withstand high pressure without leakage, high precision, high finish, cold bending without deformation, flaring, flattening without cracks and other points, it is mainly used for the production of pneumatic or hydraulic components, such as cylinder or cylinder, can be seamless pipe. The chemical composition of the quilted cylinder tube is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr.
1. Good wear resistance: The main material of the honed cylinder tube is high-strength wear-resistant alloy. Its hardness is several times higher than ordinary steel and can effectively resist wear and corrosion. Therefore, under the erosion of high-speed fluid, the honed cylinder tube can maintain good use condition for a long time, reducing the number of maintenance and replacement, and reducing production costs.2. Strong corrosion resistance: Honing cylinder pipes are mainly made of wear-resistant alloys, stainless steel and other materials, which can effectively resist the erosion of corrosive media such as acids, alkalis, and salts, and maintain the stability and service life of the pipeline. This kind of pipeline is not only suitable for conventional fluid transmission, but also for the transmission of high concentration, high acidity, and highly corrosive media.3. Good high temperature resistance: The honed cylinder tube can withstand extremely high temperatures and pressures, and its working temperature range can reach above 0°C. In high-temperature environments, honed cylinder pipes can maintain high strength and rigidity and will not be deformed or broken due to high temperatures, which affects the normal operation of the pipeline.4. Long service life: Since the honed cylinder tube has excellent properties such as wear resistance, corrosion resistance, and high temperature resistance, it has a long service life and is not easily damaged and worn, reducing the cost of maintenance and replacement. In addition, the installation and disassembly of the honing cylinder tube is also relatively convenient, which can save time and labor costs.| Speci -cation | Grade | Chemical Composition [%] | ||||||||||||||
