Why is 20Cr seamless pipe oxidized

The reason why the contradictory torque of the 20cr seamless tube decreases with the increase of fitness exercise speed is mainly due to the modification of the smoothness standard. When the object terminates, the smooth oil between the two facial cleansers is squeezed, presenting a dry or almost dry contradiction, until the speed reaches point 3, when it completely transforms into a wet contradiction. At this point, a layer of floating oil is created between the two metal material surfaces, separated by the structure of oil molecules. At this point, the torque of the contradiction exhibits a positive damping characteristic, which can prevent the object from producing rapid vibrations. The continuous expansion of fitness exercise speed and the increasing contradiction torque are due to the viscosity of the smooth oil. When the fitness exercise speed reaches the necessary standard value, the contradiction torque will not change with the speed modification. Cleaning method: Apply a layer of anti climbing oil (such as molybdenum disulfide polishing oil) in the middle of the relative velocity surface, and ensure that there is an excellent polishing standard. The 20Cr seamless pipe has the ability to resist air oxidation, which is stainless steel, and also has the ability to corrode in substances containing alkali, alkali, and salt, which is corrosion resistance. However, the level of its corrosion resistance varies with the organic chemical composition, interactions, application standards, and natural environmental substance categories of the steel itself.

Like a 20Cr seamless pipe, it has a certain high-quality anti-corrosion ability in dry and clean air, but when it is moved to the Haibin area, it will quickly become embroidered in the sea mist containing a large amount of salt; And the 20cr seamless pipe demonstrates excellent performance. Therefore, not all types of 20Cr seamless pipes can resist corrosion and rust under any conditions.
